Abstract
A frequency synthesizer of the pulse cancellation type which predicts the phase jitter that will be caused by the pulse cancellation and generates a compensation signal C which precisely compensates for the phase jitter. The compensation signal is derived directly, from a pulse train in the synthesizer which itself contains jitter, via a d.c. removal circuit DCR and an analogue integrator INT.
