3. (a) Use Matlab to generate and plot the discrete-time signal r[n] = sin (won) for the following values of uo. 8888 88 8 87 88 8 Plot each signal for 0n 63. Label each graph with the frequency Use the subplot function to plot four graphs per figure Here is some code that will do all of this. You can type the in ie-by-line at d prompt or you can create an m-file. % P3a % plot a bunch of discrete-time sine signals % The frequency will be w-k*pi/8 % Load up the k's into a vector: kvals = [-29-3-1 1 3 5 7 9 13 15 33 211; % make a counter to index the "next" k to use: next k 1 n 0:63 % the time variable % There are 12 k values. We will plot four per % figure. So we will need three figures all % together. Loop on figures for Fig num-1:3 figure (Fig-num); % selects the "current" figure % each time through this loop, we are going to do % 4 of the k's. Loop on Sub Figure number for SubFig_num-1:4 k = kvals (next-k) ; next-k = next-k + 1; % the frequency xn = sin(w*n) ; subplot (4,1,SubFig num); stem(n,xn); title (sprintf ( %d%s", k, , \pi/89) ; end % for SubF18-num end % for Fig-num 3.
