  • AGC Circuit responsive to intermediate gray level in video signal
    Patent number: 4234892
    Abstract: An AGC circuit comprises a video IF amplifier for receiving a amplitude-modulated broadcast wave of a video signal with a signal level having a constant amplitude added thereto, a means connected to the output of said amplifier for generating a video detection output signal of said broadcast wave, and a means connected to the output of said generating means for detecting said signal level from the video detection output signal and for generating an output signal representing the signal level during the existing period of the signal level. The output signal representing the signal level is applied to the video IF amplifier and is used as a biasing signal of the amplifier. The signal level having a constant amplitude is a gray level existing intermediate between a black level and a white level.
