Abstract

Um von einer Empfängerarchitektur empfangene winkelmodulierte/-getastete Trägersignale für ein durch die Verwendung der Empfängerarchitektur vorgegebenes Amplitudenspektrum des Trägersignales selbst bei kleinen Modulationsindizes demodulieren/dekodieren zu können, wird ein einem Synthesizer (SYN) des Empfängers vorgeschalteter rauscharmer Verstärker (VS) entweder in Abhängigkeit von der mit dem Trägersignal empfangenen Feldstärke abgeschaltet oder so ausgebildet, daß die maximale Ausgangsleistung des Verstärkers (VS) bei dem möglichen Amplitudenspektrum des Trägersignals nie über den Kompressionspunkt des Mischers/der Mischer in dem Synthesizer (SYN) liegt.
