Digital demodulation circuit for a frequency-modulated signal, application of this circuit to the realisation of a demodulator stage for the chrominance signal of a television receiver, and television receiver comprising such a stage

摘要

digital circuit for demodulating a signal having a modulation frequency according to the relation of x = a sin (∫ot ωot + f (t).dt + ϕo] where wo is the carrier and f (t) of the modulation signal.the
