ABSTRACT:
In a terrestrial mode of a TV having analog and digital capability, the RF gain is controlled using the TV's IF tuner output. In a digital cable mode the RF gain is controlled using the output of the TV's IF SAW filter, and in an analog cable mode the RF gain is controlled using the output of an analog demodulator.
