This circuit simulates the signal produced by a muscle, serving to adjust medical equipment. The circuit is from the 1968 Mullard. Transistors support modern equivalents.
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...
