Signal Processing - Measuring and Testing PEMF Devices for quality of Waveform, Frequency spectrum, Intensity and More.
Is Your PEMF device broadcasting a Symphony or a Cacophony?
Signal processing is a subfield of mathematics, information and electrical engineering that concerns the analysis, synthesis, and modification of signals, which are broadly defined as functions conveying "information about the behavior or attributes of some phenomenon", such as sound, images, and biological measurements. For example, signal processing techniques are used to improve signal transmission fidelity, and subjective quality, and to emphasize or detect components of interest in a measured signal.
What we way in PEMF therapy is a clear, high fidelity signal, using a rapid rise and fall waveform and delivering a WIDE spectrum of frequencies for maximum cellular resonances.

Signal transmission using electronic signal processing. Transducers convert signals from other physical waveforms to electric current or voltage waveforms, which then are processed, transmitted as electromagnetic waves, received and converted by another transducer to final form. PEMF is a SOURCE of the Signal of pulsed magnetic energy modulated with precise frequencies so that IDEALLY the human organs, tissues, cells, organelles and molecules can TRANSDUCE this energy into usable energy to recharge the cellular voltage (TMP = transmembrane potential), recharge ATP, promote microcirculation/electroporation, etc.
Ok, back to signal processing, but just know from Transduction the many ways signals can be created...
Signal processing refers to the science of analyzing time‐varying physical processes. Signal processing is divided into two categories: analog signal processing and digital signal processing.
An analog signal is continuous in time and can take on a continuous range of amplitude values that can vary in strength and quality.
A discrete‐time signal or digital signal is a direct pulse, either on or off, that conveys information in a binary form (1's and 0's)

PART 1 - Measuring Signals
Oscilloscopes and Spectrum analysers
The most commonly used test instrument that displays waveforms is the oscilloscope. This test instrument displays signals in what is termed the time domain, i.e. amplitude against time. With PEMF devices we want to look at both the time and frequency domains.
1) Oscilloscopes show use the time domains which reveal the waveform of the PEMF signal.
*** Work in to below - Throw in the DC polarity reversals every 2 minutes which deflect a compass, amplitude sweeping (looking for that resonance amplitude window), and rest time, and you will find that capturing a particular event’s wave shape will be like counting fish at a hydrodam spillway….you wait, then it shows up and goes past.
The amplitude vs sweeptime displayed by the oscilloscope defines the waveform. Dr. Fischer cites specific reasons for specific waveforms in his Cellular Ion Transport patent, and it makes sense. The accuracy of the amplitude displayed is not important when capturing waveforms, but the relative amplitudes and “squiggles” are. The response of the probes, converting the magfield back to the waveform of the current pulse coming out of the PEMF device’s accessory can be checked by using the dual trace function of the oscilloscope. Trace 1 on the output DB-15 plug, Trace 2 is H-field probe.

2) Spectrum Analyzers
Whilst this is vey useful, when testing radio frequency circuits and systems in particular, it is useful to be able to see signals in the frequency domain, i.e. signal amplitudes that appear at different frequencies.
By looking at the amplitudes of signals at different frequencies it is possible to measure the amplitudes of these signals, find what signals are present and the like.
So Spectrum analyzers allow us to analyze the spectrum of frequencies and their corresponding amplitudes (Fourier Coefficients).
Mathematically Fourier transforms allow us to convert from one to another. Signal processing is using real time measureable date, BUT if the waveform is well constructed (ie. High Fidelity) it should closely match the Fourier transforms from Time to Frequency OR from Frequency to time.
Uses for Spectrum analyzers
Spectrum analyzers are normally complicated pieces of equipment which take a little while to get used to using. However after a little familiarization, they can become very powerful tools for testing and RF equipment, or in our interests, testing PEMF devices.
The spectrum analyzer can be used for a number of tasks:
Looking at the frequency spectrum of a PEMF signal to see items like the following:
1) The overall spectrum of a modulated signal to see whether it is wide enough or too narrow, etc. If it is too wide then it could cause interference to users in adjacent channels.
2) To investigate whether any spurious or unwanted signals are present. These signals could cause interference to users on other frequencies is signals are transmitted.
3) To find out whether a signal is on the right frequency, and not in another band for example. This is important to see the spectrum of frequencies.
4) To investigate general problems with a signal. Often it can just help looking at a signal to see what a problem is. With RF signals a spectrum analyzer can prove to be the eyes for the person investigating the problem. Some cheap PEMF devices have Cheap signals that lack in quality.
5) Sometimes spectrum analyzers can be used to measure power, although power meters may be more applicable in certain circumstances. In this way we can get a clear Heatmap of a PEMF mat or applicator and the actual intensities coming off.

Filtering
Another important concept in Signal Processing is the idea of filters.
Filters are used for two general purposes: (1) separation of signals that have been combined and (2) restoration of signals that have been distorted in some form.
Signal separation is needed when if the signal is contaminated by interference, noise or other signals.
Signal restoration is used when a signal has been distorted in some form.
For raw signal data to be analyzed, information must be represented in either the time or frequency domain.

Figure here summarizes the four most common basic frequency responses.
These filters allow unaltered passing of some frequencies, while other frequencies are completely blocked. Those frequencies that pass through are called “passband,” while frequencies that are blocked are referred to as “stopband.”
The band in‐between is called the “transition band.” A very narrow transition band is called “fast roll‐off,” “The cut‐off frequency” is the frequency that separates the “passband” from the “transition band,”
The human body seems to have a low pass filtering in place, so PEMF devices

In a receiver, a bandpass filter allows signals within a selected range of frequencies to be heard or decoded, while preventing signals at unwanted frequencies from getting through. A bandpass filteralso optimizes the signal-to-noise ratio and sensitivity of a receiver.
***Lazoura, H.: The Design of Equipment to Measure the Electrical and Optical Properties of Acupuncture Points and Meridians, PhD Thesis, RMIT University, Melbourne, Australia, 2005.
Lazoura results indicated that acupuncture meridians act as filters and hence allow only certain frequencies to pass through and attenuate all other frequencies. The fact that this pass band was set to low frequencies corresponds with the characteristics of acupuncture points, and with the spectral components measured traditionally in ECG and EEG signals.
Figure Below shows the distinct spectral components of 4, 7.8 and 13 Hz which closely correlate well with the Nature’s own resonant frequencies. The correlation may indicate relationship between one’s existence and functioning as an integral part of nature and the Universe. It could also help explain the sensitivity of our bodies and mind to changes in the environment and even the universe, which has been used by our ancestors throughout time as a form of spiritual guidance and a form of healing.
Study results prove that there is a correlation between the actual Schumann resonance peaks and electro-acupunture meridians.
---
while one study proves a correlation between transfer function of Schumann resonance and electro-acupunture meridian. The results from our acupuncture meridians and EEG activity studies confirm that the human body absorbs, detects and responds to ELF environmental EMF signals. This is a classical physics phenomenon utilized in telecommunication systems.
In engineering, a transfer function (also known as system function[1] or network function) of an electronic or control system component gives the device's output for each possible input.
Transfer functions - input frequency / output amplitude. Peak amplitudes at resonance.

Sensing
Sensing is the ability of the device to detect the intrinsic electrical signal. This is measured in Volts. The larger the signal in Volts, the easier it is for the device to sense the event as well as to discriminate normal intrinsic from spurious electrical signals.
There is an inverse relation between sensing and sensitivity. The higher the sensing value, the lower the sensitivity to detect the intrinsic electrical signal. Thus, a setting of 8 mV requires at least an 8 mV electrical signal for the sensor on the electronic device to detect. A 2 mV setting will allow any signal above 2 mV to be sensed.

Slew Rate
One way of measuring the quality of a sensed signal is to look at the slew rate. The slew rate refers to the slope of the intrinsic signal (Figure 8) and is measured in volts/second.
In electronics, slew rate is defined as the change of voltage or current, or any other electrical quantity, per unit of time. This is similar to Faraday's law as it shows how rapidly a signal rises and falls.
In other cases, a maximum slew rate is specified in order to limit the high frequency content present in the signal, thereby preventing such undesirable effects as ringing or radiated EMI.
Rapid Rise and Fall Requires higher frequency...
Low frequency harder to filter because dB/dt or dV/dt.

Slew Rates in PEMF devices
Slew rate measured in volt/second. The more rapid the voltage increase, the sharper the electrogram, the higher the slew rate.
This is VERY important for a PEMF signal to be biologically active. Sawtooth and Squarewaves provide the BEST possible Slew Rate which is why you show look for a PEMF device the has these waveforms AND has them executed properly.
I say that because SOME PEMF devices on the market have squarewaves (like OMI/Vasindux) with a poor slew rate. This means their signal is poorly executed because of cheap electronics.
When the Slew rate is designed WELL , like iMRS 2000, BEMER and QRS, you get a rapid rise and fall with many ringing higher harmonics. This gives rise to a greated dB/dt which as Faraday's law showed us, yields greater Induction and greater biological effects!!

Part 2 - Creating Signals
Review of Maxwells Equation (Faradays Law of Induction)
The faster B changes (which means a Greater dB/dt), the larger the magnitude of the curl of the induced (circulating) Electric Field in your tissues for maximal Ion transport, charge separation and energy production.
This is what we said before, but now we can add the curl to the discussion because the induced electric fields in tissues will be circulating, curling and twirling eddy currents forming closed loops.
Review: The minus sign in the equation is Lenz's law stating that induced currents will oppose the change in magnetic flux.

Let's Now Look at some examples as How Faraday's Law applies to PEMF devices.
1) Importance of Magnetic Flux vs Magnetic Field Strength (Intensity) Alone
2) Importance of Number of Turns or loops in the coil ("N" from Faraday's Law)
3) Rapid Rise and Fall to give maximum induction dB/dT (ΔΦ/Δt from Faraday's Law).
4) Why sine waves are not ideal (and not natural either).(ΔΦ/Δt from Faraday's Law)
5) PEMF and how it induces EMF that charges in the body (E or EMF from Faraday's Law)

Which Waveforms Deliver Maximum Benefits?
Next there is the waveform of the signal. The signal shape is equally as important as the frequency and intensity. The NASA study demonstrated that a rapid time varying waveform is most effective for promoting healing and regeneration.
There are two waveforms that meet this criteria, the saw tooth and the square wave; and ideally you'll want a PEMF device that has BOTH. Both the saw tooth and the square have rise and fall times that are far more abrupt than a simple sine waveform or triangle waveform. Again the more abrupt the rise and fall time, the greater the biological effect.
The key is the sharp rise time and fall time of the waveform. This is the characteristic that produces ion dissociation, resonance of cell membrane receptors, and maximum access to the “biological window.” Nerve impulse waveforms like a sine or triangle wave have gradual rise and fall times and are not capable of maximum ion dissociation. These devices ignore the many studies that demonstrate the profound biological effects of waveforms with sharp rise and fall times (such as the sawtooth and square waveforms).
Great DB/Dt Sawtooth and Squarewave
Both the sawtooth signal shape and the square waveform have rise and fall times that are far more abrupt than a simple sine wave. Some PEMF companies use a simple sine wave which is BETTER than static magnetic but much less dynamic that rapid rise and fall waveforms. Also you can only get one frequency at a time with only one set of harmonics from a simple sine wave.
Note the image shown is a simple repeating waveform... The best PEMF devices like the iMRS 2000, QRS and BEMER have a many layers of complexity that is NOT repeating. Cheaper PEMF units do not do this. We'll talk about this more in the next section.
MYTH: SIMPLE SINE WAVES RELATED TO EARTH PEMFs ARE NOT FOUND IN NATURE!
SO THEY ARE NOT MORE NATURAL AND MUCH LESS EFFECTIVE (As We'll See).

Quality of Waveform - How accurate is the Fourier Series
PEMF B.S. - Not all waves are created alike...
Fourier Series To Create a Squarewave
The mathematician Joseph Fourier discovered that sinusoidal waves are the actual building blocks that make up nearly all periodic waveforms, including squarewaves, sawtooth, triangle and more.
As you carry the Fourier series out to infinity you get an ideal squarewave, but that is an engineering impossibility. The best you can do in practice is to create a GOOD approximation by expanding the series out as far as possible. Using the first four expansions gives a VERY good approximation.
I did a signal analysis on the OMI as one example and it appeared to be a very crude Fourier series creating a CRUDE squarewave (perhaps only first two iterations the bare minimum to even qualify as the first term is a sine wave.
Cheaper PEMF devices like the OMI use maybe two expansions and the quality of the signal is POOR because of thin copper wires and poor wiring.
The iMRS 2000 and other quality PEMF devices use not only more
Image below shows a squarewave created from the first four terms of the fourier seriers needed to generate a squarewave. The more terms you use, the better, but there are engineering limits.
Harmonics... Using More Terms and properly wound coils gives you MORE harmonics and a broader frequency range.

Above coefficients shows that a square-wave is composed of only its odd harmonics.
But here below a square-wave is presented by Fourier transform perspective:
What is important to note is that you get a BUNCH of frequencies all at the same time with decreasing amplitude as you get to higher frequencies... This is a ringing effect sometimes refer to as PEMF ringer devices, BUT ANY PEMF device with rapid rise and fall is a RINGER PEMF!

Circular Polarization and Polarity Reversal -
Circular Polarization - Antenna and Radio Theory
Ideal Polarization to cover all possible receiving angles. All the cells in the body do seem to have an anisotropic orientation from top to bottom but there are many local variations so a good PEMF devices will cover all bases and all angles.
Very important for both preventing acclimations AND trying all orientations and polarization angles in the body. Along with sweeping all frequencies and amplitudes within know biological windows, PEMF uses mainly circularly polarized energy that is IDEAL for transmitting signals to many varying antenna angles. But ADDITIONALLY you need to switch polarity to resonant with BOTH clockwise and counterclockwise spins.
Make sure the device switches polarity every few minutes. This is important because the body will get used to either a constant north or constant south pole polarity. This is one of the main drawbacks (amongst others) why you DON’T want a static magnetic mattress pad or pulsed magnetic therapy devices that do not switch polarity. Every two minutes is an ideal switch.
