Abstract

PURPOSE:To enable to record an FM voice signal without cross modulation and a luminance FM signal, by setting a carrier frequency of a voice FM signal to a given frequency and phase relation to a horizontal synchronizing signal frequency of a luminance FM signal. CONSTITUTION:A horizontal synchronizing signal frequency fH of a luminance FM signal separated from a composite video signal at a horizontal synchronizing separation circuit 26 is changed into a given odd number frequency with a PLL1 and frequency-divided by 1/4 at a frequency-divider 31. This output is in 1/m frequency division as the reference signal frequency and transmitted to a phase detection circuit 33. On the other hand, an voice signal is inputted from a terminal 38 and the voice FM signal outputted at a voltage controlled oscillator 36 is applied to an adder 23 and 1/m frequency divided and inputted to a detector 33. The detector 33 compares the voice carrier frequency with the reference signal frequency to be applied to a filter 34 and rhe recording of the FM voice signal without cross modulation with the luminance FM signal is made by coinciding the FM carrier frequency to the reference signal frequency.
