摘要

Abstract: A method for determining the transfer function of a continuous system from sampled responses to single and multiple pulse excitation is presented. The method is an extension of the sampled edge response method pioneered by the theoretical work of A. Papoulis in 1962 and the application of the theory to optical systems by B. Tatian in 1965. Occasions arise when pulse rather than step function stimuli are available for system excitations. In such cases, the method presented is practical for determining the system transfer function. The use of anti-aliasing filters and estimation of non-bandwidth limited transfer functions are also discussed. !7
