C) Select the statement that best describes your observation. AM modulation FM modulation 10 -10 -5 1 3 1 3 time x 103 time x10 combined message and AM signal combined message and FM signal -5 -5 -10 3 1 2 1 2. 3 time x10 time x10 a. Kvco is large enough to faithfully represent the modulated carrier s(t) b. By viewing the AM modulated plot, distortion can easily be seen, which is caused by a large AM index. c. Kvco is very small, which means that the FM index is very small, thus the FM modulated carrier does not faithfully represent m(t). d. b and c are correct amplitude amplitude amplitude
