At its core, an audio amplifier is an electronic circuit that takes a low-power electrical signal (often from a microphone or digital-to-analog converter) and increases its amplitude to a level sufficient to drive a load, such as a loudspeaker or headphones . It uses an external power supply to generate an output that is a larger, faithful replica of the input signal. Key Components of a Practical Circuit practical audio amplifier circuit projectspdf
