This circuit generates high pulses from a sinusoidal input, using SCRs for this purpose. The pulses are positive and negative, as shown in the figure and the SCRs admit equivalents.
This single channel circuit can be used with one of the many receivers that we describe in this...
We find this circuit in an old documentation, but it can be made using modern transistors. The circuit...
