1. Suppose that the modulating signal is m(t) = 2cos (2p fmt) and the carrier signal is xC(t) = AC cos(2p fct), which one of the following is a conventional AM signal without over modulation?
(A): x(t) = Ac [1 + m(t)]cos (2p fct)
(B): x(t) = Accos(2p fmt)cos(2p fct) + Acsin(2p fmt)sin(2p fct)
(C): x(t) = Acm(t)cos(2p fct)
