Abstract
A universal analog signal interface includes a pair of signal conditioning circuits, each responsive to one of a pair of analog signals presented between two inputs of each for providing corresponding pairs of output signal manifestations representative of the magnitude and the phase of the pair of signals received; the analog interface further including signal conversion circuitry responsive to each of the pairs of signal manifestations of magnitude and phase for providing a digital signal representative of the ratio of the smaller magnitude signal manifestation divided by the larger magnitude signal manifestation and for providing digital signals representative of each of the phase signal manifestations.
