QUESTION 5Select the correct statement(s) regarding amplitude modulation (AM).
| a. If the AM Index is greater than 1 (i.e., AM>1), then over modulation occurs leading to signal distortion | ||
| b. With AM, the message is captured as amplitude changes to the carriers amplitude. | ||
| c. The AM modulated signal bandwidth is dependent upon the highest frequency (fm), and frequency bandwidth, of the message | ||
| d. All of the above are correct |
QUESTION 6
- Amplitude Modulation (AM) describes a method where the baseband message is represented by carriers frequency.
True
False
QUESTION 8
- Given the following parameters, select the correct equation for the modulated carrier signal. Am=3v, Ac=3v, fm=5500Hz, fc=100MHz, m=0, c=0
| a. s(t) = 3[1+1.08 cos(25500t)] cos(2100E6t) | ||
| b.s(t) = 3[1+1cos(25500t)] cos(2100E6t) | ||
| c.s(t) = 3[1+6.5 cos(23500t)] cos(2100t) | ||
| d. s(t) = 6.5[1+0.93 cos(2100t)] cos(2100E3t) |
