To gate an integral clock pulse sequence from a continuous source without distorting pulse duration and number is not a trivial task. In most cases, a simple AND gate will cause problems, see Figure 1 ...

In pulse position modulation, the amplitude and width of the pulses are kept constant, while the position of each pulse with reference to position of reference pulse, is changed according to the ...

I have wanted to make a pulse generator for years. I know you can buy perfectly good ones, but not if you want non-overlapping outputs to drive the mosfets in synchronous-rectified dc-dc converters.
