吉布斯效应在信号处理课程教学中的仿真分析

Simulation Analysis of Gibbs Effects in the Course Teaching for Signal Processing

为帮助学生更直观地理解信号处理中出现的吉布斯效应,借助于计算分析软件MATLAB对信号处理中的信号分解与合成以及滤波器设计中出现的吉布斯现象进行了仿真,分析并探讨了吉布斯效应产生的原因及减少效应影响的方法。仿真结果可更加直观和深刻地认识吉布斯效应,对信号分析与系统设计有着重要的作用。

In order to help the students intuitively understand Gibbs effects in signal processing, Gibbs effects appearing in signal decomposition and synthesis and filter design for signal processing were simulated by using MATLAB analysis software. The cause of Gibbs effects was analyzed and the methods for reducing the inlfuence of Gibbs effects were discussed. Simulation results are able to more intuitively and profoundly understand the Gibbs effects. It plays an important role for signal analysis and system design.
