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.
We find this circuit in a 1980s documentation. The circuit can be applied to modern operators with...
This high power dimmer uses a unijunction transistor to trigger the triac. The triac is choosen...
This simple voltage-controlled oscillator generates signals from 300 Hz to 1,500 Hz with voltages from...
