通过本次实验更加深刻具体的了解信号与系统中离散卷积的运算过程.知道了信号的反褶和位移，阶跃信号x[n]在卷积中的运用，熟练掌握了卷积过程，为信号与系统后面的学习打下了基础。并且在利用MATLAB实现离散卷积的动态过程中，把课本上的理论知识与软件学习相结合，使卷积在脑海中留下更加立体生动的印象。-Through this experiment a deeper understanding of specific signals and systems Discrete convolution operation process. Know deconvolution and displacement signals, step signal x [n] in the use of convolution, convolution process mastered, for the signal and system behind learning foundation. And the dynamic process for discrete convolution using MATLAB, the theoretical knowledge and learning textbook software combine to make more three-dimensional convolution leave vivid impression in my mind.
