Abstract
A phase noise reduction circuit for reducing phase noise in an input pulse train consisting of pulses which are all of the same length and which, in the absence of phase noise, have a nominal frequency f, includes a DC removal circuit for removing a DC level from the input pulse train, an integrator for integrating the input pulse train after a DC level has been removed therefrom by the DC removal circuit and a comparator for deriving from the integrated pulse train an output pulse train containing periodic transitions at said nominal frequency. The input pulse train may be derived using a monostable circuit.
