Abstract
A load is controlled by a pulse waveform from a source. The source and load are electrically isolated by using two monostable circuits to detect the leading and trailing edge of the pulse waveform, two pulse transformers to isolate the source and the load, and a bistable circuit to reconstruct the original pulse waveform.
