We found this circuit in the May 1989 Radio Electronics magazine. The circuit can have its values changed to operate at other frequencies and the power supply must be symmetrical.
The circuit shown is from the Motorola Linear Databook of 1990. This circuit converts signals in...
In the circuit in the figure, we have the production of rectangular signals with frequencies of up...
This circuit uses a photoransistor to control the frequency for this oscillator. Power supply...
