Abstract

A receiver may receive and process broadcasting signals in digital and analog forms. The receiver may include an amplifying input stage, a digital signal processing stage and an analog signal processing stage. The input stage may receive a broadcast signal. The digital signal processing stage may process a received broadcast signal and output a first quality information signal. The analog signal processing stage may process a received analog broadcast signal and outputs a second quality information signal. An evaluation unit may evaluate at least one of the first and second quality information signals and output a control signal to the amplifying input stage.
