If you need to produce extremely fast pulses in response to an input and trigger, such as for sampling applications, the predictably programmable short-time-interval generator has broad uses. The ...

This simple circuit generates narrow pulses at about 700-800Hz frequency. The pulses, containing harmonics up to the MHz region, can be injected into audio or radio-frequency stages of amplifiers, ...

Years ago, before such a wide range of functionality was available, engineers mocked up small circuits with counters and decoders to generate the specific pulse patterns they needed. Of course, that ...
