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 we have a small general-purpose amplifier with the LM386 integrated circuit and...
The presented circuit allows to control the valve of a tap. The positioning of the emitter and the...
This circuit is from a 1956 Sylvania publication. The transistor used is germanium and the old...
