SYSTEM AND METHOD FOR GYROSCOPE ZERO-RATE-OFFSET DRIFT REDUCTION THROUGH DEMODULATION PHASE ERROR CORRECTION |
摘要 |
A circuit for processing signals from a gyroscope includes a first that generates an in-phase demodulated signal and a second demodulator that generates a quadrature-phase demodulated signal with reference to in-phase and quadrature-phase modulated signals, respectively, from the gyroscope. The circuit includes a digital processor that receives the demodulated in-phase and quadrature phase signals from the demodulators and generates an output signal corresponding to a rotation of the gyroscope along a predetermined axis with reference to the in-phase demodulated signal and the quadrature-phase demodulated signal to remove a portion of the quadrature-phase signal from the in-phase signal. |
