Feed-forward high resolution sensor measurement using low resolution ADC

Abstract

According to one aspect of the invention, a method for making relatively high resolution measurements using relatively low resolution devices includes the steps of: deriving a first anticipated measurement value; using the first anticipated measurement value as an initial feed-forward signal; comparing the initial feed forward signal to a received signal from a sensor, thereby generating a compared signal; scaling the compared signal to full scale of an analog-to-digital converter, thereby generating a scaled signal; delivering the scaled signal in binary form for computation; and iteratively performing the comparing step until the compared signal is below a predetermined threshold value.
