Question
A microwave data link has been designed to operate at 110,000 symbols per second while encoding 14 bits per symbol. The receiving equipment requires at least a 50 dB signal to noise ratio in order to operate without significant error.which of the following are true:
At least 55 kHz of bandwidth on the transmission channel are required for the attempted system.
The data rate of the designed link will be 1.54 Mbps.
If the actual signal to noise ratio is 100 dB, the system could support encoding as many as 17 bits per symbol.
There is not enough information given to determine the minimum transmission power needed to make sure an acceptable power level arrives at the receiver.
Exactly 16,384 symbols are needed to support 14 bits per symbol.
If the background noise at the receiver is -50 dBm, the receive power will need to be at least 0 dBm.
Explanation / Answer
If the actual signal to noise ratio is 100 dB, the system could support encoding as many as 17 bits per symbol.
