Question

Implement the MATLAB exercise "PAM2_eye.m" on Page 430 of the Lathi textbook. This will require the functions: "pnrz.m", "prz.m", "psine.m", and "prcos.m" on Page 428-429. 2.1 Data Pulse Trains a) Plot the data pulse train for the ideal return-to-zero case (yrz). b) Plot the data pulse train for the ideal non-return-to-zero case (ynrz). c) Plot the data pulse train for the half-sine pulse (ysine). d) Plot the data pulse train for the raised-cosine pulse (yrcos). 2.2 Eye Diagrams a) Plot the eye diagram for the ideal return-to-zero pulse (yrz). b) Plot the eye diagram for the ideal non-return-to-zero pulse (ynrz). c) Plot the eye diagram for the half-sine pulse (ysine). d) Plot the eye diagram for the raised-cosine pulse (yrcos). 2.3 Questions a) As the eye diagram becomes more "open", what happens to "inter-symbol interference", that is the chance of interference between bits? b) What is the cost of having less chance of inter-symbol interference?
