研究了一类非线性相位的单位解析信号,采用实方法给出了这类信号的一般刻画.最后,将这种情形归结为Mbius变换的一个特例.
In this paper we present a class of non-linear unit analytic signals. By using real-variable methods, we also give the general characterization of such a kind of signals. Moreover, we prove that this class of functions is just a special case of Mobius transform.
