Patent ID: 8656775

Claim:
A vibratory gyro-sensor comprising: a vibratory section; a synchronous detector which synchronously detects a detected signal from said vibratory section in timed relation to a timing signal for synchronous detection; and a timing signal output section which outputs said timing signal for synchronous detection, said timing signal output section including (a) a low-pass filter which extracts a low-frequency component of a vibration monitor signal representative of a vibrating state of said vibrating section, (b) a comparator which converts said vibration monitor signal into a binary signal using the low-frequency component of the vibration monitor signal which is extracted by said low-pass filter as a threshold value, and (c) a first phase shifter which shifts the phase of said vibration monitor signal, wherein, the vibration monitor signal as converted into the binary signal by said comparator and shifted in phase by said first phase shifter is used as said timing signal for synchronous detection.
