ABSTRACT:
A device for the compensation of dropouts in an angle modulated signal. The device comprises a variable delay line, which receives a control signal from a control unit for variably delaying said angle-modulated signal. The control unit comprises a dropout detector and a transformation means co-operating therewith for supplying an output signal which is representative of the magnitude and the polarity of the dropout. Said output signal is applied to the variably delay means as a control signal.
