Explain the trade off between bandwidth and signal to noise ratio
Answers
Explanation:
It is measured at the receiver's front end. To increase the information rate, the signal-to-noise ratio and the allocated bandwidth have to be traded against each other. For no noise, the signal to noise ratio becomes infinite and so an infinite information rate is possible at a very small bandwidth.
To increase the information rate the trade between bandwith and signal noise ratio are held.
Definition of Bandwith;
The maximum number of data is transferred over the internet. It is a part of information technology.
Definition of signal noise ratio;
Signal noise ratio compared the desired signal to the level of background noise.
Trade between bandwith and signal noise ratio;
- To occupy the smallest system the bandwith and signal noise ratio work against each other.
- Bandwith has the fixed quantity and niether can be changed. So the channel capacity is directly proportional to the signal noise ratio.
- While the channel capacity is changed by the signal noise ratio to occupy the smallest system or the allocated bandwith.
- The noise of the bandwith increases and we can observe the signal noise relation also increased in the background.
Hence, in relation to bandwith and signal noise relation they work simultaneously in reference to the channel capacity directly proportional to the signal noise ratio.
