<p>The invention relates to a receiving circuit for an information engineering receiving device, in particular a television set, provided with an improved possibility for automatically adjusting the amplification control of an intermediate frequency (IF) stage and to a corresponding method. The tuner and the IF stage are provided with an automatic amplification adjusting unit, respectively, connected to at least one HF amplifier. A strobe signal can be transmitted from the IF stage to the tuner for taking-over the amplification control. An IF signal can be produced from the tuner by means of a predetermined level limiting quantity. Said level limiting IF signal is used in the form of a reference for adjusting the automatic amplification adjusting unit of the IF stage.</p> |
