Let the message signal to a DSB-SC modulator be a multi-tone sinusoidal signal given by m(t) = A1 cos(2f1t) + A2 cos(2f2t) + A3 cos(2f3t) The carrier signal is given by c(t) = Ac cos(2fct). Develop a Matlab script to answer the followings: (a) Plot the DSB-SC modulated wave and its amplitude spectrum. (b) Find the required transmission bandwidth for DSB-SC wave. (c) Find the total average transmit power of the DSB-SC wave.
