%X In this paper, the synthetic function for the time optimal control of the secondorder discretetime system is obtained by the Isochronic Region method. Based on this function,the discrete form of tracking- differentiator is constructed. Numerical simulation shows that thisdiscrete form of tracking- differentiator can quickly track an input signal witbout overshoot andchattering and can produce a good differential signal.
