摘要
本文论述了数字信号处理中的加窗问题以及采用加窗处理的必要性,同时分别就频谱分析和LTI(线性时不变)系统设计中的加窗原理和窗效应及选窗原则等进行了较为详细的探讨.
This paper discussed the window-adding problem and the necessity to use it in the digital signal processing; In the meantime, the principle of window-adding and the window effects are discussed both in spectral analysis and in the design of LTI system; the paper also gave the principle of selecting window function.
