This tutorial paper focuses on a number of designs for perturbation (input) signals for system identification; all of the signals can be designed using software readily available on the World Wide Web. Pseudorandom signals have fixed spectra, and both binary and multilevel signals are discussed. Other classes of pseudorandom binary signals that greatly increase the number of available signal periods are described. Computer-optimized signals have spectra that can be specified by the user, and the paper deals with three types - multisine (sum of harmonics) signals, and binary and multilevel multiharmonic signals. Perturbation signal quality measures are also considered in the paper.
