Found in 1970s General Electric documentation, this circuit uses period components to control a 12 V motor. Transistors support modern equivalents according to the controlled motor.
This anti-ringing circuit was found in an English documentation from 1996. The integrated circuit is...
The figure shows how to increase the gain of the amplifier stage of the previous circuit. The...
This circuit uses unusual operational amplifiers, but equivalents can be tried. FETs can also be...
