1. The problem statement, all variables and given/known data Use MATLAB to find the convolution between a) ##f(t) = u(t) -u(t -3)## and ##g(t) = u(t) -u(t -1)## 2. Relevant equations 3. The attempt at a solution t = -10: 0.1: 10; f = heavisde(t) -heaviside(t -3); g = heaviside(t) -heaviside(t -1); t = -20: 0.1: 20; c = conv(f, g); plot(t, c) The graph of the convolution has values from 0 to 10. I don't get how the convolution can get to 10 if the functions being convolved only have maximum values of 1. I changed the line to c = 0.1*conv(f, g); and this produced the right output. Why do I need to multiply by the step size?
