Write a MATLAB code for the question below.
There is an initial signal containing 60 Hz sinusoid of amplitude 0.8 and a 150 Hz sinusoid of amplitude 1.2 corrupted by a noise - using the randn command - (zero-mean white noise with variance of 4). Plot the noisy signal in the time domain. After that compute the Fourier transform -using the fft command of the noisy signal, compute the two-sided spectrum. Define the frequency domain f and plot the single-sided...

Assign the peaks in your spectrum by:
(1) drawing what you think the structure of the product is directly
on your spectrum; (2) identifying the protons with code letters
(e.g., “Ha”, “Hb”, “Hc”, etc.), but grouping protons that give rise
to the same signal under the same label; (3) writing “Ha”, “Hb”,
“Hc”, etc., near the appropriate peaks so that the assignment is
clear; (4) identifying impurity peaks.
