Abstract

PURPOSE: To eliminate unneeded band limitation for recording and to prevent a noise reduction circuit from mulfunctioning by exercising control over the insertion of a multiplex filter corresponding to a pilot signal in an FM broadcast signal.
CONSTITUTION: When an input sound signal is an FM broadcast signal, its pilot signal is detected by detection circuit 2, whose output voltage changes switch circuit 3 over to the (a) side to supply noise reduction circuit 5 with a signal with the pilot signal removed through multiplex filter 4. Meanwhile, an input sound signal from a record, microphone, or the like includes no pilot signal, and consequently switch 3 is changed over to the (b) side to supply the signal to circuit 5 as it is.
