Suggested by General Electric in a 1980s publication, this circuit is intended for coupling alternating signals, with the transistor being polarized in its linear region.
The operational amplifier of this circuit is not very common today, because we removed the circuit...
This circuit transmits signals to an FM receiver placed at a distance of up to 200 m. The antenna...
We found this circuit in an American documentation from 1964, but it can be easily assembled...
