In the figure we have a circuit that uses unusual components, being indicated for low frequency applications. The circuit signal is generated by a unijunction transistor that oscillates at 8 kHz.
This circuit was found in the September 1976 issue of Radio Electronics magazine. The circuit is...
We found this circuit in a 1995 documentation. It operates in the 3.5 MHz band that corresponds to the 80...
This 3-decade operating range VCO was found in a 90s Popular Electronics. The circuit uses...
