Abstract: A method for suppression of vibration includes: adjusting a center frequency of a band-pass filter, and subjecting a to-be-detected signal to processing by the band-pass filter to result in a bandpass-filtered signal; performing signal processing upon the bandpass-filtered signal to obtain a converted result; determining whether a scanning process is completed, and repeating the previous two steps when a result is negative to obtain plural converted results; determining a maximum value among the converted results, and determining the corresponding center frequency to serve as an interference frequency; and setting the interference frequency as an operating frequency of a notch filter.
