We found this circuit in a 1977 factory documentation. The operational amplifiers can be 741 and the symmetrical power supply. Capacitors can be changed for operation at other frequencies.
In the figure we show an application in which the 4093 excites a stage with 4 transistors in the...
We found this circuit in a 1980s documentation. The circuit uses general purpose transistors,...
