    PWM Pulse Control

    I understand what your saying, but I was actually wondering what actually happens internally to the microprocessor/amplifier to allow it to switch so rapidly? Being totally solid state, Is it something similar to a 555 timer, which uses the rate to charge and discharge a capacitor to control...
