Fortunately they’re a very simple circuit with only one 2N3904 transistor, but the snag is they need a high voltage power supply well over 100 V. So the challenge isn’t making the pulse ...

These circuits are part of a family of circuits that include differentiators, integrators, clipping and clamping circuits, pulse-timing and delay circuits, logic circuits, and switching circuits. In ...

such as needing to use a down-converter to make the peak-to-peak frequency deviation in the pulse train more easily detectable. As is his style, he walks us through a test circuit to prove that ...
