Roots (20 points). Consider the loop-gain transfer function L(S) = TS-a)n-m where n and m are integers such that n > m and a € R. Also, consider the characteristic equation 1+ KL(S) = 0, with 0 <KER, which can be equivalently written as nam (s– an-m + K = TI (s – rj) = 0. Show that num ri=(n - m), for any 0 <KER.
Use Definition 7.1.1. DEFINITION 7.1.1 Laplace Transform Let f be a function defined for t > 0. Then the integral L{f(t)} e-stf(t) dt 0 is said to be the Laplace transform of f, provided that the integral converges. Find L{f(t)}. (Write your answer as a function of s.) L{f(t)} = (s > 0) f(t) 4 (2, 2) 1
