Abstract
Improvements introduced in the object of the main patent no. 319.453 by "A method for receiving high frequency signals, particularly those modulated in amplitude and/or phase" in which the received signal is carried through at least one mixer with an oscillator mixer to an amplifier (eg low amplifier). frequency or video amplifier) and in which in the correct tuning, the frequency of the mixer oscillator is equal to the carrier frequency of the received signal and in which according to the main patent (St 22 927 IXd/21a4, SEL/Reg 10 704) the received signal or the mixing oscillator is modulated with an auxiliary signal which is compared to produce a control voltage for tuning the frequency or phase of the mixing oscillator respectively, in a comparator circuit, with the auxiliary signal derived from the amplifier characterized in that, when video signals are received, the auxiliary signal is applied only during the retracement of the line.
