In a double sideband amplitude modulation with suppressed carrier (DSB-SC AM) system, the carrier is c(t) = Accos 2n fet where Ac> 0 and the message signal is given by m(t) = AmA(t/3) + Bmsinc²(4t) where Am, Bm > 0. Find the frequency domain representation and the bandwidth of the modulated signal. A frequency-modulated (FM) signal has the form where fe 10MHz, fm = u(t)= Au cos [2π fet + Cu sin 2π fmt] = 1KHz, and Au, Cu > 0. (a) Determine the modulation index and the transmitted signal bandwidth. (b) Repeat part (a) if fm is doubled. (1)
