Phase is the timing relationship between two different sine waves. If two generators are connected across a given load in series, and if their armatures begin rotating together at exactly the same time and speed, two different alternating voltages will be produced. In...

Class C Amplifiers You will recall that most AF amplifiers use cathode bias. The audio amplifier tubes are operated ad Class A or Class B, because we are interested in obtaining good fidelity. The Class A amplifier sacrifices efficiency for fidelity. In the case of an...
