Title: Quadrature flash digitizers and synchronous counters for conversion of analog quadrature signals to phase angle data

Abstract

The methodology and hardware used to deduce and digitally encode the phase angle Phi(t) from quadrature signals of the form S/sub 1/(t) = k(t) sin Phi(t) and S/sub 2/(t) = k(t) cos Phi(t) on an extremely fast time scale are described. Theory and experimental results are given for quadrature flash digitizers and quadrature synchronous counters. Designs for two-stage quadrature digitizers are described. Scaling formulas and design equations are given. These devices appear to be no more complex than conventional linear digitizers and synchronous counters.
