一、离散序列傅里叶变化——DTFT 1、DTFT公式 2、Matlab算法实现 function[X]=dtft(x,n,w,flag) %计算离散时间付里叶变换 %[X]=dtft(x,n,w) %X=在w频率点上的DTFT数组 %x=n点有限长度序列 %n=样本位置向量 %w=频率点位置向量 X
Open in MATLAB Online Ran in: Again, the code doesn't follow from the question. For starters, it's apparent from the question and the graphic that N = 1024. Hence the code should start with something like: ThemeCopy N = 1024; n = 0:N-1; w0 = 201/N*2*pi; % case 1 xsin ...
(3)如果x(n)是实偶序列,则其DTFT也是实偶序列; 前两个参照P3.7,第3个参照Example3.12。 一、上代码 View Code 二、运行结果 1、原始复数序列 2、共轭对称序列xe 3、共轭反对称序列 4、各自的DTFT 5、取出想要的图 一、上代码 View Code 二、运行结果 1、原始实数序列 2、分解成偶序列和奇序列。 3、...

I just started a MATLAB course and my first excercise is to write a MATLAB function that computes the DTFT of a signal x[k] at a given number of frequencies. Also a magnitude and phase plot must be made. My code: 테마복사 % X=dtft(x,phi); % % discrete-time Fourier transfo...
