| Abstract: | At first,this paper introduces the main features of 3-level pseudorandom signal PRTN and derives some useful equations about the correlation identification by using PRTN as the input signal.Furthermore,it introduces a high precision real-time identification device by using TP86A single board computer and gives the results of real-time system identification of a given one-order linear system.It proves the coincidence of the theoretical analysis discussed and the results of the practical identification obtained.Finally,some interferences often occured in the process of system identification and the elimination methods of their effects are also discussed. |
