pwm amplifier

Transistor amplifier

In general, a transistor amplifier is a circuit for amplifying an analog signal or a digital data carrier signal. For example, the output audio signal of a microphone is very weak and the audio oscillation is in a very low voltage range. With a transistor audio amplifier, its output can be increased to the standard…
