Abstract

PURPOSE:To reject the noise pulse, by interpolating the composit signal with the composit signal advanced with the phase by an a multiple time of the 19KHz pilot signal period than the composit signal. CONSTITUTION:The noise pulse detector 1 receives the output composit signal St of the frequency discrimination circuit and detects the noise pulse TN. The monostable multivibrator 2 is at ''1'' for the output for a given time T1 from the leading of the detector 1 with the detector of which output is at ''1'', and the monostable multivibrator 3 is a multivibrator in which the output is at ''1'' for a given time T2 from the trailing of the output of the multivibrator 2. Further, the delay circuit 4 delays the composit signal St for a given time TD, and the switch circuit 5 outputs the output of the circuit 4 SD(t) while the output of the multivibrator 3 is at ''0'' and outputs the signal St while at ''1''. Further, interpolatin is made with the composit signal lead in the phase by a multiple of time of the pilot signal period in 19KHz than the signal St to reject the noise pulse.
