Find the convolution using Matlab for the following signals in problem 2.40 of the text book. Discretize the signal at an interval of one. For example x(t) = 1,1,0 and y(t) = 1,1, 22.0. See the example on page 176 of the text. You can use the function conv(x,h). Plot the resulted convolution signal. a. mt)-x(t) *y(t) b. m(t)- x(t) *z(t) c. m(t)x(t) w(t) 5pts 5pts 5pts y(r) x(T) z(t) w(t) -2 1
