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.

Input control system for high frequency receiver

A signal amplifier system is provided for a mobile or portable broadcast receiver. The signal amplifier system includes an operational circuitry, a signal generator and a voltage supply. The signal generator receives a field strength signal that indicates a field strength of at least one broadcast signal. The signal generator outputs a supply voltage control signal based on the field strength signal. The voltage supply provides one of a first supply voltage and a second supply voltage to the operational circuitry in accordance with the supply voltage control signal.
