From an audio signal, this circuit gets two signals of the same amplitude and opposite phases. This setting is widely used in bridge amplifiers (BTL). Transistors may be commonly used as BC series.
This configuration uses the 4 gates of a 7401 integrated circuit. The capacitors determine the...
We found this circuit in a documentation from the 70s. The original text was kept. The oscillator...
