摘要
本文讨论了参差周期序列傅氏变换的部分基本理论,着重研究了参差周期FIR滤波器的时变特性的描述,系统的最大瞬时响应,输出序列谱,输入序列谱和滤波器频响之间的关系。
This paper presents the partial fundamental theory of the Fourier transform for the staggered perodic sequence. The time-varying property of staggered periodic FIR filter, the maximum system instantaneous response, and the relation amony the output sequence spectrum, the input sequence spectrum and the frequency response of filters are emphatically described.
