This circuit was obtained from a 1968 documentation and can be adapted to use current equivalent components. The maximum frequency depends on the components used.
This circuit changes the actuation curve of a 47k or 50k linear potentiometer so that it becomes...
The oscillator shown in the figure can generate signals between approximately 3 and 15 MHz,...
We found this circuit in a European documentation from the 90's, but the circuit is current, as it...
