ABSTRACT:
A high definition television receiver including analog and digital signal processing circuits receives an analog high definition television signal representative of digital television information. The received signal contains narrowband high priority information and low priority wideband information. An automatic gain control (AGC) signal is developed from the received analog signal by means of a root-mean-square amplitude detector.
