ABSTRACT:
The present invention is directed to a system, apparatus and method for averaging digitized phase values. In particular, the polar coordinates represented by the digitized phase values are converted to rectangular coordinates via trigonometric identities. Several coordinate values are averaged, and the quadrant information derived from the signs (+ or -) of the averaged values is used to efficiently convert the final averaged rectangular coordinates back to polar representation.
