摘　　要：分析了石英微机械陀螺的信号模型。为实现灵活的参数调整、改善陀螺的性能和进行误差补偿,提出并实现了一种用于石英微机械陀螺的数字解调系统。该系统通过对陀螺输出信号和驱动信号进行数字化,并采用定点数字信号处理器(DSP)进行解调运算,实现了对石英微机械陀螺角速度信号的检测。The signal model of quartz micro-machined gyroscopes was analyzed. A digital demodulation system for quartz micro-machined gyroscopes was proposed and realized to enable flexible parameter adjustment： improve the performance of gyroscopes and compensate the error. The output signal and drive signal of gyroscope were digitized, and the pointing type digital signal processor （DSP） was used to demodulate the signal of gyroscope. The detection of angular signal from quartz micro-machined gyroscope was realized.
