Question: Equation gives one way to write the finite-length pulse p(t) in Fig. in terms of the unit-step signal u(t). A second way is to use a product notation.
(a) Make a plot of the signal u(t - 2).
(b) Make a plot of the signal u(4 - t). Determine the region where the signal u(4 - t) is zero.
(c) Show that the product signal u(t - 2)u(4 - 0 is the same as the signal p(t) in Fig.
