Found in a 1964 Electronic Design, this circuit is intended to serve as a time base for cardiac monitors. Transistors support equivalents.
The input impedance of this circuit is very high, on the order of 4M ohm and the output impedance is...
In the same way that we can regulate the voltage in the positive branch of the circuit, we can...
This circuit can be used as a rhythmic light or as a control shield for incandescent lamps from...
