频域及时域 Gibbs 现象的实验研究

摘要

Gibbs phenomenon is a common problem in signal processing ,and there is no better way to completely eliminate this phenomenon at present .It is difficult for students to understand the Gibbs phenomenon deeply and comprehensively in the course of signal processing .In this paper ,the reason of Gibbs phenomenon in frequency domain and time domain is analyzed respectively , and then the experimental research method is designed .%Gibbs现象是信号处理常见的问题，目前还没有较好的办法能完全消除这种现象。学生在学习信号处理课程时，很难深入、全面的理解Gibbs现象。在实验教学环节，应侧重于从频域和时域对Gibbs现象产生的原因进行系统的分析，并在此基础上由学生参与设计该现象的实验研究方案。
