Basic Signals, Systems, and the DFT Overview One of the best ways to learn the material in this course is through using a computer. MATLAB is a powerful software package which is very useful for generating, processing, and plotting signals, and insight into many signal processing concepts can be gained through using it. This project is primarily designed to get you familiar with using MATLAB. If you have already completed the project Basic Signals and Systems , you only need to do exercises 3 and 4. You may find the diary command useful for maintaining a history of your MATLAB session. Other commands you may find useful include subplot , orient tall , and orient landscape . To get information about a function and its usage, use the MATLAB help command, e.g. help subplot , help filter , etc. Basic Signals 1. Generate and plot (using MATLAB'S stem command) the sequence x[n] = (0.95) n cos( π /20 n) for 0 ≤ n ≤ 63. Note that MATLAB'S indexing for the first element starts with 1 and not
