a) Calculate and plot the DTFT of ?[?] = sin( (?/ 4)?) / ?? * cos ( ?/2 ?) by hand.
b) By using a 2x1 subplot, plot ?[?] signal defined in Question 1 in the first row. Take ? between -100 s and 100 s and limit x-axis between -20 sand 20 s. Be careful about when ? = 0. What is the value of ?[0]? While plotting ?[?] please write an if statement for ? = 0. After that, write a MATLAB code that calculates and plots the DTFT of ?[?]. Then, plot the DTFT of ?[?] in the second row of the subplot. Take 1000 equally spaced frequency values between -2π and 2π by using linspace. Do not forget axis labels.
