DETECTOR, SENSOR, ELECTRONIC APPARATUS, AND MOVABLE BODY

摘要

PROBLEM TO BE SOLVED: To provide a detector, a sensor, an electronic apparatus, a movable body, or the like, capable of effectively attenuating components corresponding to detuning frequencies while suppressing a signal delay or the like.SOLUTION: A detector 20 includes: a drive circuit 30 for receiving a feedback signal from a vibrator 10 and driving the vibrator 10; a detection circuit 60 for performing detection processing on the basis of the signal from the vibrator 10 and outputting detection data; and a digital signal processing section 110 for performing digital filter processing with respect to the detection data from the detection circuit 60. The digital signal processing section 110 performs processing of a band elimination filter for attenuating a component corresponding to a detuning frequency &Dgr;f=|fd-fs| corresponding a difference between a drive side resonance frequency fd and a detection side resonance frequency fs of the vibrator 10 with respect to the detection data.
