Smoothing device of the phase jumps likely to affect a timing signal, and an application to the filtering dejustification jitter of a digital bit stream.

摘要

Smoothing device of the phase jumps likely to affect a timing signal, and previously reported with a signal indicating phase shifts, characterized in that it comprises: & br / - means (1) of the delay to be applied to the pulses of the steady rhythm signal a delay which, in the absence of phase shifts, is constant and equal to a nominal value, referenced no, and, in the presence of the phase jump, becomes instantaneously, for the pulse of the steady rhythm signal affected by the phase shift equal to nc + n or to nc - n follows that the phase jump has an amplitude equal to - n or + n, where nc denotes the delay applied to the pulse of the steady rhythm signal of the affected by the phase shift, and then, for a set of pulses, which varies progressively, for the phase jump in question, in the case of nc + n to nc or nc - n to nc, the nominal value n is determined so that the delay values remain positive in the case of phase jumps consecutive positive, & br / - means (2), controlled by said indication signal jumps of the hase type, in order to determine the values of delay.
