Multifrequency excitation method for rapid and accurate dynamic test of micromachined gyroscope chips. [PDF]
A novel multifrequency excitation (MFE) method is proposed to realize rapid and accurate dynamic testing of micromachined gyroscope chips. Compared with the traditional sweep-frequency excitation (SFE) method, the computational time for testing one chip ...
