This circuit was found in documentation from the 1970s. The transistor supports modern equivalents. L1 with C4 determines the frequency range of the signals that will be produced.
This circuit came out in a publication called Electronics Handbook of 1993. The circuit shows how...
This oscillator can generate signals up to a few megahertz depending on the crystal used. Actually...
The drive levels of this shield are opposite to the previous one. The photo-transistor can be of...
