Title: Fm modulating signal reproducing device
Inventor: YASUMURA HIROTO
IPC: H04N5/94
Filed: 1983-05-31
Abstract: PURPOSE:To eliminate a noise caused by a signal omission so as to reproduce an original signal faithfully and exactly by detecting an omission of a reproduced FM modulating signal, and controlling a response time of a phase synchronization. CONSTITUTION:A reproduced FM modulating audio signal of an input terminal 1 is inputted to a phase comparing circuit 10 through a BPF 2, the circuit 10, a VCO 11 and an LPF 12 constitute a phase loop PLL, and an output signal of the VCO 11 is phase-locked to a signal inputted to the circuit 10. When the input signal of the circuit 10 is omitted by a drop-out, a drop-out detecting signal is obtained in an output of a drop-out detecting circuit 6, and in a period in which this signal is generated, a time constant varying circuit 13 increases a time constant of the LPF 12, delays a response of the PLL, and makes it go slowly toward a free-run frequency of the PLL. Accordingly, an input signal exists in an FM demodulator 3 even in a drop-out period, a noise in case of inputting from a no-signal is not generated in the output, and a transient by an LPF 4 can also be prevented.
