System and methods for processing signals in a television system are disclosed and may include measuring relative power of RF carriers over a full bandwidth of one or more received TV channels. The method may also include determining based on the measured relative power, whether the one or more received TV channels includes a digital component or an analog component without demodulating the received TV channel. It may be determined whether the one or more received TV channels includes a digital component or an analog component without synchronizing and/or decoding the one or more received TV channels. The method may further include tuning to the one or more received TV channels. It may be determined whether an applied power gain for the one or more received TV channels is a maximum power gain.
