Task 1 2.5 1.5 2 1.5! Triangular, x1 Rectangular, x2 0.5 0.5 0 -2 -0.5 0 2.5 -1.5 -1 1 1.5 0.5 1 1.5 Time (seconds) -0.5 0 0.5 Time (seconds) Figure 1 (a) Figure 1(b) Given xl(t) is a triangle and x2(t) is a rectangular signal: ii. By calculation determine the additional of both signals z(t) = xl(t) + x2(t) and verify by MATLAB By calculation evaluate the convolution result, y(t) = xl(t) = x2(t) or y(t) = x2(t) *xl(t) and verify by MATLAB
