I need an expert to choose the correct answer and provide proof with a drawing or a law or something from a reliable source. 1. In AM, 50% modulation indicates that ,33.3%,11.1%). of the total transmitted power is in the sidebands (0%,50% 2. To obtain coherent detection in AM receiver, an extra signal is added to the modulated signal, this signal (PLL, IF carrier, pilot carrier, subcarrier). called 3. The output spectrum of a modulator includes upper-side, lower-side frequencies, and the carrier frequency. (balanced, standard amplitude, SSB, none of the above) 4. When a signal is multiplied by the unit step function, (the positive time range is suppressed, the negative frequency range is suppressed, the negative time range is suppressed, the positive frequency range is suppressed). 5.
