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.
In the figure we have an inductance bridge for values between 1 and 30 uH at a frequency of 5 MHz....
This traditional monostable configuration is from a Motrorola documentation from the 70s. The...
