Abstract
PURPOSE:To discriminate a reproduced FM signal without malfunction by using a HOLD control circuit holding the preceding state when an input signal is a signal having a prescribed threshold value or below and outputting the information of the signal when the level is the threshold value or over. CONSTITUTION:An input signal is inputted to a peaking circuit 1 and given to an automatic signal discriminator 4 after passing through AGC circuits 2, 3. The automatic signal discriminator 4 is added with a signal changeover time constant circuit at the S-VHS side comprising a resistor 15 and a capacitor 13 and a time constant circuit for signal changeover at the VHS side comprising a resistor 16 and a capacitor 14 after the signal comparison and detection. The signal inputted to the automatic signal discriminator 4 is subject to comparison and detection of FM spectrum and to which of the S-VHS or VHS system the signal belongs is discriminated and an output signal in matching therewith is outputted via a HOLD control circuit 12.
