ABSTRACT:
The same AGC voltage as is developed in a television receiver to control the gain of its signal translating stages is additionally utilized by the described circuit to automatically de-peak its video response during the reception of relatively weak signals. The video response is automatically returned to its normal peaked condition during the reception of stronger signals--again, under control of the AGC voltage.
