Frequency Shifting Property in MATLAB Complete Prove (Code + Output)

 Frequency shifting Prove: DFT{x(n)e^(j(2*pi/N)nl = X(K-l)

You can prove Frequency Shifting Property in MATLAB of any sinusoidal signal. To do Linearity with any signal in Matlab, simply open and create a new Script (.m file) in Matlab.


Step 1:

Open MATLAB << Then on the top left corner click on the File option << Click New << Then click Script. 


Step 2:

Now write the following Matlab code given below of Frequency Shifting into the new script (.m file) and save the file in the Matlab directory with any name you want.




n = 1:5;

x = sin(n);

l = -2;

w = 2*pi/N;

x1 = x.*exp(-1i*w*l*5);

N = length(x1);

f = fft(x1,N);




N1 = length(x);

f1 = fft(x,N1);

[y n1]=sigshift(f1,n,1);




 Step 3:

Now Run the code, after you have saved the file.
