In conducting electrophysiological and medical investigations, in registration of bioelectric processes in particular, various types of converters permitting notation of bioelectric signals can be used with an ordinary tape recorder instead of costly magnetic registrators. A frequency converter with whose help it is possible to register bioelectric processes in a frequency range of 0.1 to 10(3) Hz with a conversion error of not more than 1.5 per cent is proposed.
