Matlab Teaching Study in "Digital Signal Processing" Course

Digital Signal Processing is a highly theoretical course,difficult to understand the knowledge points for the process of teaching secondary school students learning boring and other issues,the Matlab software into classroom teaching,FIR filter window function design method for teaching examplesknowledge point that the graphical presentation.In the experimental teaching to the Matlab software as a platform to design filter in accordance with the principles of programming of the window function design method using the Matlab Signal Processing Toolbox provides fir1 function filter,as well as call filter design and analysis toolbox provides graphics user interface design filter.Teaching effectiveness of Matlab into the teaching process,not only allows students to intuitively understand and in-depth understanding of the theoretical knowledge of digital signal processing and analysis methods,can also improve students' practical ability and the ability to analyze and solve problems,improve the quality of teaching.
