Abstract
PURPOSE:To enable to commonly use an LPF for recording an playback, by providing a switch switching a recordig color video signal and an ouput of an FM demodulator and locating a color signal rejecting trap between the LPF and an FM modulator. CONSTITUTION:At recording, a color video signal inputted from an input terminal 1 is selected with a switch 4, it is supplied to an LPF5 for common use with recording and playback and it is subject to band limit, and color signal is rejected by changing the sharpness of recording Q of a color signal rejecting trap 6, and it is outputted via an FM modulator. At playback, a playback FM signal inputted from an input terminal 2 is demoudlated into a video signal at an FM demodulator 3 and selected at the switch 4 and supplied to the LPF5, where the FM carrier component is rejected and signal processing such as noise suppression is made at a playback signal processing circuit 9 for output.
