1. Use graphical aid to compute the convolution below: y(t) = x(t)*h(t) = = L x (7)h(t -1 x (1) 0 II. Plot the following function x(t) = 10rect X(T)h(17)dT. +(17)-10rect () III. Compute and then draw the following convolution: 8(1-2)* [u(t)-3u(t-1)+2u(1-2)] A(z) 0 IV. Determine whether or not each of the LTI systems whose impulse responses are specified below are BIBO stable. 1-h(t) = et 2-h(t) = eu(-t) 20 1 TU n=1 1 V. Using MATLAB: A- Plot the following function for N=1,3,30,100, and 1000. x(t) = 10- sin (177) 2
