| Abstract: | The research on fractional-order system and its applications to many fields of science and engineering has gained increased interest in the field of signal processing.This paper introduces the transform and characters of signals about fractional transform from the viewpoint of the Laplace transform,and analyzes related characters on continuous fractional-order linear systems.The results discussed in this paper suggest that fractional-order linear systems have more flexibility than traditional integer-order linear systems in signal processing. |
