Capacitors are silver-mica or ceramic types, and values are expressed in The resistors are 1/2-W carbon units. Traditional Class D amplifiers require an external lowpass filter to extract the audio signal from the pulse-width-modulated (PWM) output waveform. The choice of modulation scheme is important, but it is often blown out of proportion: A good modulator will not save a poor design - it represents just one piece of the puzzle. Following the logic of an op amp's control pins, we observe that if the voltage from a signal source driving the positive input were to go positive, the output of the op amp would start to go very positive.
