1. Let U() = exp(-\SD). (a) Let up(t) = Reexp(2pifct)u(t)]. Use the complex baseband method to compute the energy of Up (this will not depend on f.). (b) Let V (f) = exp(- f - fel+exp(-\f+fel. Find the exact energy of Vp. Does it depend on fc? (c) Let V(f) be the spectrum of complex envelope for V, that is supported on the smallest interval of frequencies. Find V(). Does VS) depend on fe? (d) Apply the baseband method of computing energy to V. 1. Let U() = exp(-\SD). (a) Let up(t) = Reexp(2pifct)u(t)].
