Abstract How to determine sampling rate of highfrequency deformation instrument is studied. At first observation frequency range including passband and transition band should be determined based on the resolution of instrument dynamic range, and then sampling rate is determined according to the highest frequency and Nyquist’s Sampling Theorem. Finally the result is verified by simulation experiment.
