给出了S阶偶项信号和离散Fourier变换之间的关系。提出了最小平方偶项卷积反演方法。

Abstract

A new concept

s-order even term signal

is proposed and its properties are discussed.The relationship between cepstrum and s-order even term signal of a signal is given.When a signal is finite

the expression of the Z transform of its s-order even term signal is derived.When signal is perioic

the relationship between its s-order even term signal and its discrete Fourier transform is obtained.Finally

the least square even term decon-volution method is presented.
