Abstract
An input circuit is provided for a television receiver for amplifying and transforming the input signals into an intermediate frequency signal. The output of the mixers is fed via intermediate-frequency bandpass filters to respective decoupling diodes, which are switched on depending on the selected receiver frequency range. The output of the decoupling diodes is fed to an impedance transformer such as an emitter follower and its output in turn is entered into an intermediate-frequency amplifier.
