     In lab#6 you found convolution (h(t)*x(t)) using three methods (analytically, graphically (area using rectangular approximation or quad), and MATLAB in-built function).  h(t) = sin(pi t) (u(t) - u(t - 1))  x(t) = 1.5(u(t)-u(t - 1))  You found that the shape of the plot of h(t)*x(t) agrees in all the three methods but the magnitude does not, why so? Explain how those three methods calculate convolution. 
  
  Solution
what are results ?
