In one embodiment, the present invention includes a method for digitally
detecting a first signal strength corresponding to a multi-channel
spectrum of an incoming radio frequency (RF) spectrum and digitally
detecting a second signal strength corresponding to a selected channel of
the incoming RF spectrum. Based on these values, one or more one gain
stages of a receiver, such as a satellite television receiver for the
incoming RF spectrum, may be controlled. Other embodiments are described
and claimed.
