添零方式对有限长序列离散谱的影响

Effects on the Discrete Spectrum of the Finite Sequences with Different Zeros-Padding Modes

讨论了在有限长序列前、后 ,中间补零以及两点之间插入零对该序列离散频谱的影响并给出利用 MATLAB语言进行验证的方法和结果。

Zeros-padding can be operated in different ways. The zeros-block can be inserted to the head, the tail or any in-between position of the finite sequences. Zeros-paddingcan also be operated in the interpolation mode. The effects of these different zeros-padding ways on the discrete spectrum of the finite sequences are investigated in this paper. The corresponding verification procedure and results with MATLAB are detailed addressed.
