In a vibratory microgyroscope, the synchronous demodulation of the secondary (sense) resonator output is a critical part of the signal processing. This is because different nonidealities can corrupt the resulting signals, including the angular velocity information. The effect of these nonidealities is revealed in the demodulation process. In this paper, issues related to synchronous demodulation a... View full abstract»
