代码说明:

   设计一个模拟信号(几个不同频率简谐信号之和,再加一个白噪声) 用不同的采样频率把信号离散(满足和不满足采样定理), 画出信号波形; 分别作信号的谱分析(幅值);对比采样频率的影响; 选用不同窗函数对同一个信号作谱分析,比较分析。(signal process using matlab)

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • sort
    Conceptually, a merge sort works as follows Divide the unsorted list into n sublists, each containing 1 element (a list of 1 element is considered sorted). Repeatedly merge sublists to produce new sorted sublists until there is only 1 sublist remaining. This will be the sorted list.
