代码说明:

  1)编写DFT子函数(计算并画出幅频特性),以后可调用。 2)N=32,M=32,128,256时,分析频率分辨率、频谱的光滑程度。 3)N=64,256,512时,分析频率分辨率和频谱的光滑程度。 (1) the preparation of DFT Functions (calculated and drawn amplitude-frequency characteristics), the future can be called. 2) N = 32, M = 32,128,256, the analysis of the frequency resolution, the degree of smooth spectrum. 3) N = 64,256,512, the analysis of the frequency spectrum resolution and the degree of smoothness.)
