Question

Write a MATLAB program to generate and save the following signal in file x4.wav. Plot a section of the generated signal. x4(n)-02sin(2nfnT), n = 0, 1, 1023 where, f-1000Hz, and T-1/8192 sec. This is the question:(here please help) Modify the program for x4(n) to generate the signal sequences for the following reconstructed sampling frequencies: a. fs-8f b. fs=4f c. fs 1.5f d. fs=1.3f e. fs-1.1f Now use x4(n) sequences to reconstruct the signal using plot and spline functions of the MATLAB. Compute, in each case, the signal frequency from the reconstructed signal. Prepare a table as follows to determine if there is any aliasing effect. Sampling Frequency Reconstructed Signal Frequency Aliasing/ No Aliasing 8f 4f 1.5f 1.3f 1.1f .9f .8f Describe your observations regarding aliasing and the frequency of the reconstructed signal in each case.

Explanation / Answer

for n=0:1:1023

x4n=0.2*sin(0.766990*i);

Similarly for other values of f, calculate in the same way
