1.Select the correct statement(s) regarding the FM Index.
|
a. Δf represents the amount of frequency that the carrier wave can change in order to represent the baseband (information/message) signal |
||
|
b. β=(KvcoAm)/fm is a ratio that has no units |
||
|
c. the larger the FM index, the greater the frequency bandwidth |
||
|
d. all statements are correct |
2. Select the correct statement(s) regarding viewing an information signal in time and/or frequency domains.
|
a. only the viewing a signal in the time domain is important since the transmission/carrier frequency is an assigned parameter |
||
|
b. observing the signal in the time domain does not give you information regarding the capacity or bandwidth of the signal |
||
|
c. a signal observed in the frequency domain provides information regarding signal amplitude and the periodic or non-periodic nature of the signal |
||
|
d. all of the above are correct
|
3. Select the correct statement(s) regarding frequency division multiplexing (FDM).
|
a. FDM can aggregate either analog or digital channels |
||
|
b. FDM produces a broadband signal consisting of combined modulated channels separated by guard channels that contain no information |
||
|
c. The received FDM aggregate goes through a demultiplexing process that recovers the separate modulated channels at the receiver |
||
|
d. all statements are correct
