摘　　要：应用Mobius变换,对5种常用数字信号的傅里叶级数进行逆变换运算,得到正、余弦函数,以及一般周期信号对信号的展开.求得在这些非正交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 five digital signals in common use is operated by applying Moebius transformation. As its results, the authors obtain the expansionsps of sine, cosine function and their general periodic signals into these digital signals; and solve also the expanded coefficent of the non-orthogonal functional family which are perpendicular to the expanding base function family.

关 键 词：MOBIUS变换 傅里叶级数 逆变换 周期信号 信号展开 非正交函数族 展开系数
