Abstract

Three computer programs, all freely available on the World Wide Web, for designing and generating different classes of perturbation signals for system identification are described. Two of the programs are for designing pseudorandom signals, which have fixed power spectra. The first program is for designing signals based on five known classes of pseudorandom binary or near-binary sequences, and the second program is for designing pseudorandom signals based on maximum-length sequences, both binary and multilevel. The third program is for designing multilevel multiharmonic signals, in which the user can specify the harmonic pattern required, and a computer optimization routine is then used to meet the specification as closely as possible.
