通信原理实验噪声产生设计与实现

Design and Implementation of Experimental Noise Generated by Communication Theory

噪声及其产生是通信类课程教学中的重要内容。由于噪声的产生涉及到频域分析和时域分析的理论,在理论教学和实验教学中,学生普遍反映白噪声和有色噪声的产生设计是难以掌握和应用的。为此,我们对实验室通信实验噪声产生进行了设计。结合噪声的特性分别对色噪声和白噪声的产生进行分析,从工程应用的角度,以实验为例设计了噪声产生实验系统。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。

The noise is generated and communication courses teaching important content. Since the generation of noise relates to the theory of frequency domain analysis and time domain analysis, theoretical teaching and experimental teaching, students generally reflect the design to produce white noise and colored noise is difficult to grasp and applications. To this end, we have laboratory experimental communication noise designed. Combined with noise characteristics respectively colored noise and white noise generation are analyzed from the point of view of engineering application, experimental noise Case designed the experimental system. For noise design teaching some guidance and help students better understand and apply.
