A modulator for a clock pulse generator receives clock pulses from a clock pulse source, which clock pulses exhibit a reference phase. Delay circuitry is connected to the clock pulse source and includes n tap connections, each connection providing a clock pulse that is delayed by a different phase delay from the reference phase. A multiplexer is connected to each of the n tap connections and provides an output manifesting the clock pulses. A selector circuit controls the multiplexer to sequentially connect any sequence of different ones of the n tap connections to the multiplexer's output, whereby the output manifests a series of clock pulses which have different phase displacements from the reference phase.
