ABSTRACT:
In a device comprising a linear frequency demodulator, the demodulation threshold is improved for demodulation of signals which have been modulated by a digital data item and have an energy line at the carrier frequency. To this end, the received modulated signal is not applied directly to the demodulator but added within an adder circuit to a signal corresponding to the carrier-frequency line which is obtained by means of a carrier recovery circuit. The output signal of the adder circuit is applied to the input of the linear frequency demodulator.
