摘要：
Based on the Hilbert transform, measurement errors of the amplitude and frequency of a vibrating signal of variable frequency are studied. The chief factors affecting measurement error of the parameters of a signal were determined by means of numerical modeling. The use of a frequency response model of a vibration isolator in the form of a Chebyshev digital filter confirmed the effectiveness of the Hilbert transform. The results of numerical modeling were successfully verified during field tests of the vibration isolator at an electrodynamic workstation.
