Exercise: Use MATLAB to generate the sinusoidal waveform: x(t) = 3 cos(1200) Consider the frequency of this sinusoid and use this information to select an appropriate time-step and time array that will allow this signal to be correctly represented and displayed on a new MATLAB figure window (display 4 periods of this wave only). Now set up an appropriate frequency array and use the fft() and fftshift() functions to generate and plot the Fourier Transform (magnitude spectra)...

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...
