We found this transistorized circuit in a 1985 documentation. The circuit can operate with voltages from 9 to 12 V and the adjustment of the operating point or input sensitivity is done in P1.
This mini siren, found in a 2003 publication, powers a small piezoelectric transducer, but a...
In the figure we have the way to implement a sinusoidal oscillator with the 4093 IC. The component...
This circuit can be used in a single optical link or optical communication system and even using an...
