Abstract
A timing pulse generator for producing timing pulses the period of which is variable. In the timing pulse generator, a plurality of reference pulse trains are produced which have the same frequency as each other, but different phases from each other. Then, each of the pulses comprising the final timing pulses to be produced is created by suitably selecting one of the pulses from among the reference pulse trains, sequentially.
