We use modulation in communication system for many reason, one of the reason for using it in AM is: A. The message signal can transmitted faster with modulation compared to the same signal without modulation. B. To attach interference to the modulated signal in order to transmit it through the medium C. The modulator enhance the noise in the modulated signal using a band pass filter D. The modulator allows controlling the phase of the carrier signal, thus controlling the carrier phase. E. To control the demodulator on the receiver and extract a message signal F. To obtain a active transmitting and receiving of the modulated signal through the antenna
