| 摘要 |
The proposed device for electrophysiological analysis of biological objects contains two measuring electrodes, a reference electrode, a voltage repeater, a phase splitter, an automatic switch, a synchronous detector, a low-pass filter, a voltmeter, a low-frequency oscillator, and additionally, a high-frequency signal amplifier, a frequency-adjustable heterodyne, a frequency mixer, and a differential amplifier. The reference electrode is connected to the common point of the device circuit. One of the measuring electrodes is connected to the input of the voltage repeater, and the second electrode is connected to the input of the phase splitter. The antiphased outputs of the phase splitter are connected to the corresponding inputs of the switch. The output of the oscillator is connected to the control inputs of the switch and the detector. The output of the detector is connected to the input of the filter. The voltmeter is connected to the output of the filter.
