ABSTRACT:
A method of modulating the pulse width of a pulse width signal in response to an analog signal. The steps include changing the analog signal to a digital signal, changing the digital signal to a number of counts, changing the number of counts to a time delay, and then using the logic circuit to combine the time delay with a pulse with modulated input to change the pulse width of an output signal.
