Question 2 (20 marks) Create with the assistance of MATLAB and its associated toolboxes a discrete-time domain plot with noise added of the square wave from Q1. You may assume that the wave was sampled at f = 600 Hz with NFFT=8192 discrete-time samples and that you may use the MATLAB function, "randn" to add noise to the square wave. Figure Q2 serves as a guide to construct the time-domain plot. (Hint: notice that our waveform plot constructed will be constrained by the sampling frequency and hence a perfect square wave cannot be reproduced) (a) Compose the MATLAB codes used to generate both the discrete-time noisy square wave (using a horizontal time scale 0 ≤ t ≤ 0.5s) as well as the single sided frequency log magnitude plots./n(b) (10 marks for the codes) Prepare the discrete-time (time domain) and log magnitude (in dB) single-sided frequency plots from the MATLAB codes of part (a). (10 marks for the plots)
