Problem 2 (Digital PAM and Eye Diagram) MATLAB IN THIS PROBLEM, YOU ARE NOT ALLOWED TO USE MATLAB FUNC- TIONS rcosdesign AND eyediagram AS WELL AS comm AND Commscope. 1. Generate a digital PAM signal and its eye diagram by following the steps: (a) Generate a double-polarity random sequence with length 300 for 2 bits/symbol transmission. How many different pulse amplitude values can there be? What are those values? Explain. (b) PAM-modulate the sequence via raised cosine pulses with T, = 1 s and B = 1. Write your first 10 elements of your sequence and plot the first 10.5 seconds of PAM-modulated signal. Assume that the sampling rate f, for PAM-modulated signal is 500 Hz. Don't forget to label axes. (c) Plot the eye diagram for the PAM-modulated signal. For this, you should be careful about the following aspects which you should apply in your code: In an eye diagram plot, horizontal axis (time) starts from -T, and finishes at T The diagram is superposition of plots of each 2T, interval from the signal. The nth interval should start from (n-1)T, and finish at (n+1)T., where n is integer
