Abstract
A control circuit for a resonating rotation sensor has a pair of closed loop controls for independently controlling component traveling waves of a resonant pattern in a ring shaped resonant member. Frequency and phase quantities of the independent traveling waves as well as time dependant quantities thereof indicate total rotation angle, rotation raze and rotation direction.
