摘要
An HDTV receiver includes an AGC system that develops an RF AGC voltage that is derived on an analog basis and an IF AGC voltage that is derived on a digital basis. The digital voltage is developed from an error signal that comprises the most significant bits of a continuously operated large accumulator that is supplied with the algebraically combined output of the digital signal and an AGC reference number.
