Found in a 90s Electronic Design, this circuit can generate sinusoidal signals from 0.1 Hz to 25 kHz with low distortion using a MA292 from Maxim.
This circuit uses a capacitor to store energy. The capacitor is charged by closing S1 by a moment. Them,...
This circuit is both a signal injector and a signal follower. A key selects the operating mode. The...
The difference between this circuit and the previous one is that it uses PNP transistors. The...
