Lab Task 1: i) Write a Matlab code to find the magnitude spectrum of a square wave. Also plot the square wave and corresponding frequency domain representation of a square wave. Take t=0:0.01:2*pi. ii) Take N as an input number from user and consider only odd harmonics (kodd) and t=-n: 1/1000: n. Use Gibb's phenomenon to Plot x (t) against "t". Your output should look like as follows: MATLAB CODE and O/P: Making a Square Wave using 99 Harmonics 0.8 0.6 0.4 Time (sec) Making a Square Wave using 500 Harmonics Time (sec) a 0.4 02
