Answer with computer MATLAB

1. Write MATLAB code x and perform the following: a) Generate a sine wave of 2KHz with sampling frequency of 22KHz and plot it (10 Marks) b) Add a colored noise centered around 4.5kHz to the generated sinewave, and use suitable FIR filter to filter the noisy signal. Plot noisy and filtered sine wave. (10 Marks) c) Plot the magnitude and phase of waves before and after adding noise. (10 Marks) d) Perform filtering using overlap add method of linear filtering. (10 Marks) e) Provide critical reflection on the results obtained from part b), c) and d) (10 Marks) f) Demonstration of the above results in MATLAB (10 Marks)
