Abstract
PURPOSE:To output the synchronizing signal terminal voltage in a television signal by a switch which is changed over by a synchronizing signal, and to compress a low frequency superposed signal contained in the signal, by said output. CONSTITUTION:A television signal which a low frequency signal has been superposed on, and has been provided to an input terminal 1 is led into an output terminal 3 through an amplifier 2. A part of the signal is led into a synchronization separating circuit 6 by a changeover switch 4. The changeover switch 4 is controlled by a synchronizing pulse which has been separated from the synchronization separating circuit 6, and a synchronizing signal section and other section connect a television signal and constant voltage to a shaping circuit 5, respectively. A signal which has been integrated by the shaping circuit is supplied to an inverted input terminal of the amplifier 2, of which a negative feedback loop is constituted. A degree of compression to a low frequency component is decided by a CR time constant of the shaping circuit 5 and an amplification degree of the amplifier 2.
