Abstract
PURPOSE:To miniaturize a device of a sound processing system by constituting a filter which a signal passes through before being recorded in a magnetic tape at the time of recording, and a filter which a signal passes through before being subjected to a frequency demodulation at the time of reproduction, of the same filter. CONSTITUTION:The titled device is constituted so that a low-pass filter by which a sound signal brought to a frequency modulation by two kinds of different carrier-frequencies by a recording system, and through which said signal passes before going into a recording amplifier 5, and a band pass filter through which a mixing frequency modulated sound signal outputted from a pre-amplifier 9 by a reproducing system passes before being subjected to a frequency demodulation can be used in common. In such a way, a substrate area required for constituting this circuit can be decreased, a device of a sound processing system can be miniaturized, and also, since the number of parts can be decreased, the cost can be reduced.
