A DSP-based (digital-signal-processing-based) measuring technique of jerk is proposed in this paper. By analyzing the frequency characteristics of jerk, we design a low pass digital differentiator suitable for jerk measuring. The digital differentiator is a linear-phase FIR system, and has the advantages of low order, favorable low frequency performance and good suppression of upper band frequencies. A measuring device has been developed based on this measuring technique, and has been used in practical applications. The accuracy and stability of the measuring device have been verified by experiments, which also approved the good performance of our DSP-based measuring technique of jerk.
