14. Laplace transform monotonicity properties. Let f and g be two real-valued functions (or signals) defined on {tt 20). Let F and G denote the Laplace transforms of f and g,respectively. We will assume that f and g are bounded, so the Laplace transforms are define d at least for all s with Rs > 0. (a) Suppose that f(t) ≥ g(t) for all t≥ 0. Is it true that F(s) ≥ G(s) for all real, positives? If true, explain why. If false, provide a counterexample. (b) Is the converse true? That is, if F(s) > G(s) for all real positive s, is it true that f(t) ≥ g(t) for t≥ 0? If true, explain why. If false, provide a counterexample.
