Purpose
The purpose of the paper is to apply a novel technique for the simulation of nonlinear systems subject to
modulated chirp signals.
Design/methodology/approach
The simulation technique is first described and its salient features are presented. Two examples are given to
confirm the merits of the method.
Findings
The results indicate that the method is appropriate for simulating nonlinear systems subject to modulated chirp
signals. In particular, the efficiency and accuracy of the method is seen to improve as the chirp frequency
increases. In addition, error bounds are given for the method.
Originality/value
Chirp signals are employed in several important applications such as representing biological signals and in spread spectrum communications. Analysis of systems involving such signals requires accurate, appropriate and
effective simulation techniques.
