Abstract

PURPOSE: To suppress disturbing pulses easily by inhibiting sampling in a period from the detection of disturbing pulses from a stereo composite signal until the arrival of pulses synchronizing with a subcarrier.
CONSTITUTION: If disturbing pulse P is included in a subcarrier at its peak position, sample holding circuit 8 sampes disturbing pulse P and sends its sampling output to sample holding circuit 10. On the other hand, disturbing pulse P is detected by detection circuit 13 to set FF14 and sampling signal C2 arriving in succession is inhibited from passing through gate circuit 12. Therefore, the previous held value is being held as it is.
