In amplitude modulation, the modulation index mu, is kept less than or equal to 1 because.A. `mgt1`, will result in interference between carrier frequency and message frequency, resulting into distortion.B. `mgt1` will result in overlapping of both side bands resulting into loss of information.C. `mgt1` will result in change in phase between carrier signal and message signal.D. `mgt1` indicates amplitude of message signal greater than amplitude of carrier signal resulting into distortion. |

Answer» Correct Answer - B::D Here `mu=(A_(m))/(A_(c))` when `mgt1` overlapping of both side bands takes place and it results loss of information and alos amplitude of message signal will be greater than amplitude or carrier signal which results destortion. |
