Based on the analysis of the influencing factors of the attenuation measurement, the relationship between the sampling frequency of the attenuation measurement system and the system accuracy, sampling frequency and system measurement range is determined. Under the premise of ensuring the accuracy of the system, the sampling frequency is selected by the vibration frequency. Utilizing the linear phase characteristics of the finite impulse response (FIR) filter, analyze the effect of FIR filter on signal phase, the results show that FIR filter can eliminate DC bias and noise at the same time, and does not affect the phase characteristics of the signal.
