Filed: 1985-11-06
Abstract: PURPOSE:To make unnecessary an oscillator within a circuit and an element attached from outside at the time of forming an integrating circuit by counting directly with a counter, a chrominance subcarrier, after it is shaped in waveform to make a rectangular wave, and generating a horizontal blanking pulse. CONSTITUTION:A video signal inputted to a video signal input terminal 1 is inputted to a synchronizing signal amplitude separator circuit 2. The output of the separator circuit 2 is sent to a horizontal separation amplifier circuit 3, and only a horizontal synchronizing signal is obtained at the circuit, being given to a reset pulse generating circuit 7. Meanwhile, a sine wave signal is outputted from a chrominance subcarrier oscillator 17 required for a television receiver, and the sine wave signal is inputted to a waveform arranging circuit 6, and is formed as a rectangular wave signal, being sent to a counter 5. The counter 5 generates a pulse with the number of counts optimum for making a horizontal blanking pulse from rectangular wave supplied from the waveform arranging circuit 6, and outputs the horizontal blanking pulse to an output terminal 8.
