thankss roro

the problem is Design and Demonstrate a pulse width modulator. The input to the modulator will be a sinusoidal signal at 100 Hz. The input must be varied over a 10 to 1 voltage range. The output must be a pulse train; with the width of teh pulses being a function of the input voltage.
