Title: Signal defect section detector
Inventor: USHIO FUSAO
IPC: G11B20/18
Filed: 1978-03-01
Abstract: PURPOSE: To prevent malfunction of the defect detecting circuit owing to synchronising signals, etc. by decreasing the detection sensitivity of the defect section before and after the sections including repetitive signals.  
     CONSTITUTION: Any defect in input signal is drawn out as a change in voltage by the output of an LPF 5 and a part of the output of a preamplifier circuit 2 is demodulated by an FM modulating circuit 8 and passes through a defect compensating circuit 9, after which it is separated of synchronizing signal in a synchronous separator circuit 10. A pulse generating circuit 11 generates the signal which determines the section where the sensitivity of the circuit detecting the defect is lowered and a level detecting circuit 7 detects the defect by detecting that the input voltage exceeds a certain level, by its detection sensitivity decreases according to the pulse signal from the circuit 11. The defect in the modulated signal having been detected is compensated by the circuit 9. Thereby, the malfunction of the defect detecting signal by the repetitive signal of the synchronizing signal, etc. may be prevented.
