# 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.
