摘　　要：应用Mobius变换对 3种常用数字信号的付立叶级数进行逆变换运算 ,得到正、余弦函数及一般周期信号的数字信号展开 .求得在非正交数字信号基函数上的展开系数 ,以及与展开基函数族相正交的非正交函数族 .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.
