Abstract
A pulse width modulation analog to digital converter can accommodate both wide band AC analog input signals and DC analog input signals. If the frequency of the input signal is much higher than the conversion rate of the PWM analog to digital converter, then the output digital pulse is of constant width versus the analog input signal amplitude. If the frequency of the analog input signal is lower than the conversion rate, then the output digital signal is a train of variable width pulses whose width tracks the amplitude of the analog input signal.
