Signal calibration device and process to evaluate signals from signal producing circuits and adjust one to give a required comparison

摘要

A signal calibration device comprises at least two signal-producing circuits (12,14,16,18,20) and means (24-56) to evaluate the signals and control at least one circuit so that signal comparison is adjusted to correspond to a predetermined value. Preferably the means are delays, registers and comparators. An Independent claim is also included for a process to calibrate the signals using the device above.
