Abstract
A digital receiver includes a mixer stage receiving a carrier signal S(t) and delivering an intermediate frequency signal S.sub.FI (t) to a demodulation stage. The mixer stage is furnished with a PLL circuit for generating a signal at a given frequency. The digital receiver further includes a phase noise digital correction stage for tapping off a noise signal .phi..sub.n (t) generated by the PLL circuit in the mixer stage and for compensating the noise signal .phi..sub.n (t) in the demodulation stage.
