Ten signals, each requiring 3000 Hz, are multiplexed on to a single channel using FDM. How much minimum bandwidth is required for the multiplexed channel ? Assume that the guard bands are 300 Hz wide.
Correct Answer: B
Question 832 Explanation:
Each signal requires——> 3000Hz
Then 10 signals will require———-> 30,000Hz.
We need one guard between any two channels. So the number of guards required is 10-1=9.
1 guard band——-> 300Hz wide
9 guard band——–> 2700Hz wide.
So total bandwidth required = 30,000+2700
= 32,700.
Then 10 signals will require———-> 30,000Hz.
We need one guard between any two channels. So the number of guards required is 10-1=9.
1 guard band——-> 300Hz wide
9 guard band——–> 2700Hz wide.
So total bandwidth required = 30,000+2700
= 32,700.
30,000
32,700
33,000
None of the above
