Select the correct statement(s) regarding amplitude modulation (AM). a. If the AM Index is greater than 1 (i.e., µAM>1), then over modulation occurs leading to signal distortion b. With AM, the message is captured as amplitude changes to the carrier’s amplitude. c. The AM modulated carrier bandwidth is dependent upon the baseband signal’s frequency bandwidth d. All of the above are correct
1. Select the correct statement(s) regarding amplitude modulation (AM).
|
a. If the AM Index is greater than 1 (i.e., µAM>1), then over modulation occurs leading to signal distortion |
||
|
b. With AM, the message is captured as amplitude changes to the carrier’s amplitude. |
||
|
c. The AM modulated carrier bandwidth is dependent upon the baseband signal’s frequency bandwidth |
||
|
d. All of the above are correct
|
2. What is true about the frequency bandwidth of a modulated electrical or electromagnetic (EM) signal?
|
a. signal bandwidth is only determined by the frequency of the unmodulated carrier wave |
||
|
b. modulation technique and the amount of information transmitted determines the signal’s bandwidth |
||
|
c. only the baseband signal determines frequency bandwidth; i.e., modulation technique has no impact on bandwidth |
||
|
d. a and c are true
|
3.Regarding carrier modulation, identify the carrier signal variable(s) that can be modified to represent the original baseband information signal.
