Select the statement that best describes the resultant wave forms. a. The AM signal appears to faithfully represent the message m(t). b. The FM index is small, and it is difficult to see FM frequency changes. c. The FM signal sFM(t) amplitude does not change, which is to be expected since carrier amplitude does not represent the message m(t). d. All statements is correct.

Select the statement that best describes your observation. a. The FM modulated carrier signal appears to faithfully represent the message m(t) b. Kvco is much smaller, and as a result the FM Index is very small. Changes in the FM signal are difficult to see. c. Changes in Kvco results in FM signal amplitude changes. d. All of the statements are correct
