Found in a 1967 EEE, this circuit generates a constant amplitude signal, stabilized by a zener diode. The circuit can operate with voltages from 18 to 22 V.
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...
