Title: Impulsive noise removing device
Inventor: HAYASHI KATSUHIKO
IPC: H04N5/93
Filed: 1986-11-28
Abstract: PURPOSE:To remove satisfactorily an impulsive noise such as the switch noise of an FM demodulating signal with a simple circuit constitution by selecting respective stage input signals through a multi-stage delaying device. CONSTITUTION:From a pulse generating device 60 of a control part 54 where a rotary head switching signal, etc., are inputted to a terminal 56, a pulse G is outputted which comes to be H for a switch noise period, and a counter 55 counts a clock. The counting result comes to be an address, a ROM57 is accessed and a switch 53 is controlled. When a pulse G is L, an FM demodulating signal before a noise to input to a second delaying device 52 does not occur is selected as an interpolating signal, while the counted value of the counter 55 is from '0' up to a prescribed value, the FM demodulating signal before the noise to output from the delaying device 52 does not occur is outputted as the interpolating signal, and when the counted value of the counter 55 comes to be the prescribed value or above, the input of a delaying device 51 is selected. Consequently, with a simple constitution to eliminate a filter, a suitable interpolation is executed and the switch noise of the FM demodulating signal is satisfactorily removed.
