Abstract

PURPOSE:To avoid the effect of abnormal pulse, by stopping the sampling by consecutive two sampling pulses at least, for the sampling by the third pilot signal after the detection of abnormal pulse. CONSTITUTION:The sampling signals c, c' are given to the sample hold circuits 9, 10 via the gates 11, 12. The abnormal pulse in the stereo composite signal is detected at the abnomral pulse detection circuit 13. When the abnormal pulse is detected at the abnormal pulse detection circuit 13, the detection signal is output and the timer circuit 14 is started, a signal is output for a given time (e.g., time corresponding to one period of pilot signal), the gates 11, 12 are closed with this signal and the passage of the sampling signals c, c' is blocked. Thus, if abnormal pulse is detected, the two samplings after that are stopped.
