Abstract:
Systems and methods are disclosed for automatic gain control (AGC) for analog television signals using feed-forward signal path delay. Adjustments to the AGC frequency response are achieved by introducing an intentional delay in the signal path of sufficient length to allow time for measurement of a horizontal sync pulse level and for application of a feed-forward amplitude correction based upon this measurement to the same horizontal line.
