栅栏效应在连续周期信号谱分析中的研究
发布时间：2018-11-28 07:36
【摘要】：离散傅里叶变换是计算机对信号频谱进行分析的理论基础,在《数字信号处理》这门课程中进行了详细的理论推导。学生在对这部分内容做实验的过程中,往往会忽视实验结果里面出现的一些由栅栏效应引起的细小差别。本文重点阐述连续周期信号频谱由栅栏效应导致的误差并提出相应的改善方法。文章还结合了实际的例子在MATLAB环境下进行了分析和验证。
[Abstract]:Discrete Fourier transform (DFT) is the theoretical basis for the analysis of signal spectrum by computer. The theoretical derivation is carried out in the course of Digital signal processing. In the course of doing experiments on this part, students tend to ignore the small differences caused by the fence effect in the experimental results. This paper focuses on the error caused by the fence effect in the frequency spectrum of the continuous periodic signal and puts forward the corresponding improvement methods. The paper also analyzes and verifies it in MATLAB environment with practical examples.
