This 100 kHz oscillator was found in a 1966 Motorola publication. The transistors are of types suitable for the generated frequency and L1 / C1 depend on that frequency.
This circuit generates a pulse of approximately 1 second when the light incident on the sensor...
We found this powerful amplifier that uses common transistors in a 1998 documentation. The power...
This circuit is from 1994 documentation. It consists of a control for several DC motors that are...
