DIFFERENTIATION: For the signals x(t) in Problems (1-2), (a) Compute the fomula for and (b) sketch the signal’s derivative x'(t) = x(t). If necessary, use the Differentiation Product Rule: (f.g)’ = fg + fig’, or “RUD”, e. g u (t) = 8(t). In your plots, label both axes, and indicate key values of time and amplitude. (1) X(t) = 4 rect ). (Hint: express rect(t/10) in terms of the difference of Two unit step functions.) ( 10 points) (2) X(t) = 12 e 1. ut). (10 points)
