<p>Inertial rate sensor and method in which a drive signal is applied to a rate sensing element, a pickup circuit is coupled to the rate sensing element for providing an output signal corresponding to movement of the rate sensing element, digital logic calibrates the rate sensor and detects the occurrence of faults in the rate sensor, the rate sensing element is utilized as a frequency reference for providing a system clock signal for the digital logic, a fixed phase relationship is maintained between vibration of the rate sensing element and the system clock signal, the system clock signal is filtered to eliminate responses to spurious transitions during a period following application of operating power to the sensor, and the digital logic is reset in synchronization with the system clock signal. <IMAGE></p> |
