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 .
