A method for receiving high frequency signals, particularly those modulated in amplitude and/or in phase, in which the received signal is carried, through at least one mixer with a mixer oscillator, to an amplifier (for example a low amplifier). frequency or a video amplifier) and in which with correct tuning, the frequency of the mixer oscillator is equal to the carrier frequencies of the received signal, characterized in that the received signal or the mixer oscillator is modeled with an auxiliary signal that is compared to produce a control potential for tuning the frequency or phase of the mixer oscillator respectively, in a comparator circuit, with the auxiliary signal derived from the amplifier.
