Abstract
A method and apparatus is provided for the tuning of the resonant circuits of a communications receiver. The frequency f.sub.D is generated with an additional oscillator, which frequency is then mixed with the receiver oscillator frequency, of which three frequencies fo, fo+f.sub.D, fo-f.sub.D are formed and are applied to the antenna output. The frequency f.sub.D, which is evaluated as a narrow band, is generated by mixing at the intermediate frequency output. A maximum balancing is provided over all high-frequency circuits. The acceptor circuits are tuned to fo and fo+f.sub.D (N+5, N+11) for obtaining maximum damping of the oscillator frequency and of the mirror frequency, where N+5 and N+11 represent mirror frequencies.
