EE-322 Computer Experiment 1 Discrete-time signals and sampling Due : April-23, 2009 1. Simulate the signals shown below in Matlab. Then plot the following sequences using sub-plots: Attach the plots with your answers. Verify your answers with hand-calculations (6 plots) a) 1 2( ) ( )x n x n b) 1 23 ( ) 2 ( )x n x n c) 1 2( ) ( )x n x n d) 1( 1)x n e) 1 2( 1) ( 1)x n x n   f) 1 2( 1) ( 1)x n x n  Note: Use ”help subplot” or ”doc subplot” inside Matlab to learn more about using sub-plots to show all cases in the same page. Example: > > x1=[0 0 0 1 2 -1 0.5 -2 0 0]; % The extra zeros are needed to match the length of x2 >> n = -4:1:5; % the indices also match that of x2 >> stem(n,x1,’filled’); % the values show up in filled circles >> ylabel('x_1(n)'); xlabel('n'); % Labels the y-axis and x-axis >> title('x1 signal') % Puts the title at the top Create the shifted the signals as follows: >> x1_shift_right1(1:10) = 0; >> x1_shift_right1(2:10) = x1(1:9); >> x2_shift_left1(1:10) = 0; >> x2_shift_left1(1:9) = x2(2:10);
