Metatron hunter 4025 can evaluate level of information background noise around destructed biological objects. Trigger sensor is a device that registers information background noise from biological objects. Trigger sensor is a broadband noise generator. Oscillator diode 2G401V is used as noise generator. Noise generator, after it adjusts to resonance frequency of biological object, allows to get frequency-resonance characteristics of noise from researched object in standard range of frequencies. Received signal may be sent to oscillator or computer for further frequency spectral analysis.
