The paper describes investigations of a possibility to increase the accuracy of laser ring
gyro (RLG) by removing noise introduced by the mechanical dither system in the RLG
output signal with the composite digital filter. Composite digital filter consisting of sev-
eral barrier (notch) digital filters with optimal barrier frequency was modeled. The ex-
perimental results show that a composite digital filter including three-section notch digi-
tal filter can effectively remove the dither signal.
Keywords: laser gyroscope, digital signal processing, digital filters, vibration frequency
stand, dithering, dithering removing, barrier (notch) digital filter.
