“随机信号分析”中噪声产生设计的研讨

Discussion on Noise Design of Random Signal Analysis Course

摘要: 噪声及其产生是随机信号分析教学中的重要内容。由于噪声的产生涉及到谱分析和最小相位系统的理论，从而导致学生在设计白噪声和色噪声时容易产生错误。本文首先分析噪声的特性，然后分别对色噪声和白噪声的产生进行分析，最后以实验为例设计噪声的产生。文章对于噪声产生设计的教学有一定的指导作用，并且有助于学生更好地理解和应用。

Abstract: Noise and its generation are important contents in the teaching of random signal analysis. The generation of the noise involves the theory of spectrum analysis and the minimum phase system, students tend to make mistakes in the design of white noise and color noise. This paper firstly analyzes the characteristics of the noise, and then analyzes the generation of color noise and white noise. Finally, this paper takes design experiments as examples. This paper has some guidance to the teaching of the noise generation design, and it is helpful for the students to understand and apply it.
