ABSTRACT:
Two circuits carry out the beating of a modulated signal, with first and second signals, respectively, each having substantially the same frequency as the carrier of the modulated signal but phased-shifted relative to one another by 90.degree.. A commutator controlled by a control circuit alternately selects the signals resulting from the beating. The selection is responsive to the amplitudes of the signals in order to avoid losses of information due to amplitude peaks under a prefixed threshold which may be caused by frequency differences between the signals which are beat.
