This circuit uses three inverters to generate a rectangular signal whose frequency depends on R1 and C1. The circuit is from a March 1996 Electronics Now.
We can control the frequency of an oscillator from digital circuits or from the output of a...
We recommend adding a 470-ohm resistor in series with the potentiometer in this dimmer circuit...
We found this circuit for old tape recorders in the December 1972 Radio Electronics magazine. The...
