RUNDFUNKEMPFAENGER MIT NICAM-DECODER

2.1 The invention relates to a broadcast receiver having a PSK demodulator (17) and an AGC circuit (1) for automatic gain control. The invention is based on the object of providing a high-quality audio signal to the broadcast loudspeakers when a modulated digital audio signal is received in a broadcast receiver of this type. 2.2 According to the invention, the broadcast receiver exhibits an AGC circuit (1) and a PSK demodulator (17) for demodulating a DAB- or NICAM-coded and modulated audio signal, the demodulator being a part of a DAB or NICAM decoder (16) as a rule, and the AGC circuit being arranged in the path of the DAB or NICAM signal, and a control voltage quantity can be derived for the gain control at an output of the demodulator. The signals at the I and Q outputs of the demodulation filter of the QPSK demodulator preferably form the control voltage quantities. 2.3 Broadcast receiver or television receiver with DAB or NICAM decoder.
