EAV and bioresonance terminology
Bandpass, Band filter
A bandpass is a rather complex electronic unit. Its purpose is to narrow the range of frequencies at its output. It is analogous to a narrow slit in a wall that allows only a small section of the whole spectrum of light to pass.
Empirical studies have shown that using such a bandpass significantly improves EAV measurements by bioresonance. Results are significantly better than when using either the simple transmission of all waves at the same time or the old high-pass or low-pass filters.
With bioresonance, a bandpass either scans the frequency range periodically or is adjusted to certain specific frequency settings—depending on the application. Different methods are used with different devices and even within the functions of a given type of device.
Every classic bioresonance device should, in our opinion, have such a bandpass. There are several different techniques, some with more math behind them, others with less. Holimed uses so-called High-Q filters in its bioresonance devices. These are filters that are narrowband and remain narrowband throughout the entire frequency range to be processed. Narrowband bandwidth means that the frequencies allowed through the bandpass are highly selective in this context.
Other, older and simpler techniques utilize “textbook filters” in which the frequency selectivity decreases at higher oscillation frequencies. This means that the width of the band of frequencies that are allowed through the bandpass becomes wider and wider at higher frequency ranges. This means that the left and right edges of the bandpass become wider as well. However, these are the areas in which phase changes and phase errors occur. Because such behavior is detrimental to bioresonance, Holimed does not use such filters.
