Pulse counting works by generating a narrow, fixed-width square wave pulse at a set point in the received FM signal’s waveform, usually at the zero-crossing point. Since the frequency of the ...

Pulse forming networks (PFNs) collect electrical energy over a relatively long period of time and then release this stored energy quickly, as a short-duration, relatively-square pulse. Typically, ...

The outputs of the HEDS-6500 are two single ended square waves in quadrature. The HEDL-65XX outputs are differential. The HEDS-6540/HEDL-6540 also have a third channel index output in addition to the ...
