Abstract
A signal converter for use with a moveable mechanical device includes input means for receiving a multi-bit digital signal indicative of a position of the moveable mechanical device, a processor having means for converting the multi-bit digital signal into a pulse-width modulated signal, and a low-pass filter that creates an analog voltage corresponding to the position of the moveable mechanical device from the pulse-width modulated signal. A method of creating an analog voltage corresponding to a position of a moveable mechanical device includes the steps of receiving a multi-bit digital signal indicative of the position of the moveable mechanical device, converting the multi-bit digital signal into a pulse-width modulated signal, and creating an analog voltage corresponding to the position of the moveable mechanical device by filtering the pulse-width modulated signal.
