Abstract

A digital pulsed phase locked loop (DPPLL) provides exact measurements of echo phase, time, and/or position delay as well as echo amplitude. These exact measurements provide better and more reliable results that directly benefit the many real world applications for the DPPLL. The DPPLL permits simultaneous tracking of multiple echo pulses and considerably improved echo selection and sampling.
