ABSTRACT:
A bias modulation amplitude monitoring system for a rotation sensor having a pair of output signal component detectors to provide magnitudes of the corresponding frequency components in that signal which are used by a component relationship determination arrangement capable of adjusting the output signal to have a selected value in a range of values for a selected rate of rotation thereof, and to correct variations therein, and having a reset arrangement capable of resetting the system if the output signal indicates an unwanted phase modulation amplitude.
