  • Synch responsive agc utilizing A-D converter
    Patent number: 5157493
    Abstract: Disclosed is an apparatus for the reception of video signals with a variable gain amplifier to hold the video signal between pre-determined limits. To control the gain of the amplifier, there is provision for a circuit that keeps the amplitude of the line synchronization pulse substantially constant. This circuit has, for example, an analog/digital converter with an output, one bit of which represents the sign of the difference between the line synchronization pulse and its prescribed value.
