audio amplifier IEEE PAPER 2022
audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels faithfully, efficiently, and at low distortion. signals must be amplified (via amplifiers) in order to drive a speaker and produce sound properly. Amplifiers increase signal power and drop impedance to drive speakers appropriately.
In this research, a novel procedure for automating control of audio amplifier sound volume is proposed. Tones with several known frequencies are monitored using fast Fourier
