Audio Signal Amplifier Circuit. Speaking of incoming audio signals we have used two 10k input resistors to get the audio signal and as we are using a single supply we have attached a potentiometer to offset the zero signal present in the input audio. For both a and b the electrode input goes into the instrumentation amp and from there into the op amp.

All we have left to do here is to amplify the distortion of the circuit output. A pwm pulse width modulation signal is generated by comparing the audio signal with a 100khz triangle wale. Problem with preamp on audio amplifier.
Diy esp32 based audio player diy music players are fun to build and we previously built a few music players using arduino and a dedicated mp3 module.
The signal goes in to the base junction then amplified and out the emitter junction. Distorted output signal. Input signal and distortion circuit output. The classification of an amplifier depends upon the size of the signal large or small its physical configuration and how it processes the input signal that is the relationship between input signal and current flowing in the load.
