This oscillator produces a modulated signal using a unijunction transistor. We found it in an American documentation from 1965. The circuit modulates in frequency the generated signal.
This CMOS oscillator includes the frequency divider to generate a 400 Hz signal and a 1.6 MHz...
The power of this germanium transistor audio output stage is a few tens of milliwatts. The circuit is...
The circuit shown consists of a single switched power supply. We found it in English...
