This circuit was obtained from an American documentation from 1976. The circuit has a dynamic range of 100 kHz. FETs may be replaced by current equivalents.
In this circuit, which uses only diodes, we have both simultaneous functions. The diodes are...
The presented circuit can excite small piezoelectric transducers or ceramic buzzers. These...
We found this basic oscillator configuration with two operational in Motorola's 1978...
