Abstract
A procedure for obtaining a proper rational approximant of the transfe r function of a delayor is suggested. In particular, the step response of the unity-feedback system with the delayor in the direct path is f irst approximated by truncating the Fourier series expansion of its pe riodic component, and then the corresponding direct-path rational tran sfer function is derived, thus arriving at a stable Blaschke product.
