Abstract:
A method for processing a detection signal of a vibratory inertial force sensor is disclosed. This method improves detection accuracy of the vibratory inertial force sensor. A detection circuit of the vibratory inertial force sensor removes harmonic component from signals synchronously wave-detected, and amplifies the resultant signals, and then smoothes the amplified signals. A vibratory inertial force sensor adopting this method is also disclosed.
