Abstract
Embodiments described herein provide a method of modulating an input light beam of a fiber optic coil of an IFOG. The method includes intermittently jumping the phase step of a feedback signal to suppress dead band. Jumping the phase step includes: creating a jumped phase step during a first cycle of the IFOG, the jumped phase step having a whole value configured to cause a phase jump in the feedback signal and a fractional value corresponding to the fractional value from a phase step of a cycle immediately preceding the first cycle. Jumping the phase step also includes generating the feedback signal from a sum of the bias modulation value and the jumped phase step.
