Abstract

Abstract Translated from German Bei einem Autoradio mit einer Schaltungsanordnung zur Analog/Digital-Wandlung eines Zwischenfrequenzsignals wird ein Sigma-Delta-Wandler mit einer Taktfrequenz getaktet, die derart bemessen ist, daß ein ganzzahliges Vielfaches und ein benachbartes halbzahliges Vielfaches der Taktfrequenz das Frequenzband des Zwischenfrequenzsignals einschließen. In a car radio with a circuit arrangement for analog / digital conversion of an intermediate frequency signal, a sigma-delta converter is clocked at a clock frequency which is dimensioned such that an integer multiple and an adjacent half-number multiple of the clock frequency include the frequency band of the intermediate frequency signal.
