Could someone tell me how to build the pulse width modulator of D amp ,with discrete parts only?.
i have couple of questions.
should i use self oscilating or one that compares the audio signal with a triangular wave???
how can i create the triangular waveshape with high frequency in my circuit to compare with the audio signal using discret parts.
could someone please provide me with a schematic??

You can make a PWM modulator by comparing a signal with a triangle waveform.
Look here to see how you can build a discrete triangle generator
