Abstract
The present invention includes a system that has been developed to vary the starting and stopping of a pulse train of arbitrary phase without glitches, spurious pulses, or spurious change in duty cycle. This is accomplished by a system for generating a gated periodic waveform, the system includes a generator for generating a periodic waveform of adjustable phase; a device for providing a delayed enable signal based on the phase of the periodic waveform so that the gated periodic waveform can be started and stopped without creating undesirable changes in the gated periodic waveform; and a logic element for generating a gated periodic waveform based on the delayed enable signal and the periodic waveform of adjustable phase.
