[Reduction of recovery time of an amplifier of bioelectric potentials with an RC-circuit].
Capacitive electrodes produce low-frequency distortions of signals in the course of electrophysiologic measurements. One of the possible ways to compensate low-frequency noise consists in connecting a compensating RC-circuit across an amplifier output. As a result, a recovery time is reduced under interference as compared to an amplifier having similar frequency response yet in the absence of the compensating circuit provided amplifier signals are limited. Presented in the paper relationships demonstrate applicable limits of the given compensating method. The results may be used in designing ultralow-frequency amplifiers with the isolating RC-circuit in the input.
