The inverse transform of Fourier series of three digital signals in common use is operated by applying Moebius transformation. As its results, the authors obtain the expansions of sine, cosiue and their general periodic signals into these digital signals,and solve the expansion coefficient on base function of non orthogonal digital signal, and solve also the non orthogonal function family which are perpendicular to the expanding base function family.
