This circuit was obtained in a 1968 manual of General Electric. The components used are of the time, but they admit equivalent. Observe the optical feedback system for control.
The width of the pulses produced by the oscillator in the figure is determined by the value of R1,...
We found this approximately 1.5 kHz oscillator in Texas Instruments technical documentation. The...
This circuit was suggested by old French documentation, but it can be used as a shield, in which...
