| 中文摘要: |
| 针对学生对卷积和相关概念不清的问题,结合生活现象,本文设计了回声信号处理综合实验。实验内容包括回声产生、回声特性分析、回声消除,它将难以理解的卷积、自相关、互相关概念有机地串在一起,帮助学生理解和应用。实践表明,理论推导和实验编程相结合有助于学生将所学的知识融会贯通,且学生在做与生活密切联系的综合实验时,积极性高,收获大。 |
| 英文摘要: |
| A comprehensive experiment of echo signal processing is designed to solve the students’ confusion over the concepts of convolution and correlation. It concludes echo signal production, echo characteristics analysis, and echo cancellation, which can chain the incomprehensible concepts of convolution, autocorrelation, and cross-correlation together. It is helpful for students to understand and apply these concepts. Through the theoretical derivation and the experimental programming process, students can thoroughly master the knowledge. Students have high interests to do experiment closely related to our life and they have great benefits. |
