Dual axis vibratory rate gyroscope

A signal-processing circuit for a dual-axis vibratory rotation-rate sensor has a digitally programmable bandwidth. An analog-to-digital converter (ADC) converts analog sense signals to digital signals at a high sampling rate. The results of successive ADC conversions are accumulated for a user-programmable number of conversions. By accumulating a number of samples, the sense signals are averaged which improves the signal-to-noise ratio and smoothes the output signal. Alternatively, accumulating a smaller number of samples allows the user to improve the response time of the sensor, allowing the user to set the number of samples that are averaged enables the user to control the effective bandwidth of the sensor. The accumulated conversions are also are scaled by unit-specific calibration factors in order to accommodate for unit to unit variations, so that the rate output will be consistent across a number of sensors.
