Abstract

BROADCAST RECEIVER WITH A DIGITAL DECODER.THE INVENTION CONCERNS A BROADCASTING RECEIVER WITH A PSK DEMODULATOR (17) AND AN A.G.C. CIRCUIT (1) FOR AUTOMATIC AMPLIFICATION REGULATION. IT IS THE OBJECT OF THE INVENTION, WITH A BROADCAST RECEIVER OF THIS TYPE AND FOR RECEPTION OF A MODULATED DIGITAL AUDIO SIGNAL, TO MAKE AVAILABLE AT THE BROADCASTING LOUDSPEAKERS A HIGH QUALITY AUDIO SIGNAL.ACCORDING TO THE INVENTION, THE BROADCAST RECEIVER POSSESSES AN A.G.C. CIRCUIT (1) AND A PSK DEMODULATOR (17) FOR DEMODULATING A DAB OR NICAM CODED AND MODULATED TELEVISION AUDIO SIGNAL, WHEREBY THE DEMODULATOR IS, USUALLY, PART OF A DAB OR NICAM DECODER (16), AND WHEREBY THE A.G.C. CIRCUIT IS SITUATED IN THE PATH OF THE DAB OR NICAM SIGNAL, AND A REGULATING VOLTAGE VARIABLE FOR THE AMPLIFICATION REGULATION CAN BE DERIVED FROM AN OUTPUT OF THE DEMODULATOR. THE SIGNALS AT THE I-AND Q-OUTPUTS IN THE DEMODULATION FILTER OF THE QPSK DEMODULATOR PREFERABLY FORM THE REGULATING VOLTAGE VARIABLES.BROADCAST RECEIVER OR TELEVISION RECEIVER WITH DAB OR NICAM DECODER.
