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.
In the figure below we have a typical circuit for applying a current sensor that can be used in...
This RF preamplifier for the 450 MHz band was found in an amateur radio documentation from the...
We find this circuit in an American 1980s documentation. Modern equivalent integrated circuits can be...
