Noise Figure Solution

STEP 0: Pre-Calculation Summary
Formula Used
noise_fig_amplifier = Maximum Possible S/N Ratio/Actual S/N ratio at Output
F = S/N/S/Nout
This formula uses 2 Variables
Variables Used
Maximum Possible S/N Ratio- Maximum Possible S/N Ratio is the S/N ratio
Actual S/N ratio at Output- Actual S/N ratio at Output is the ratio at output
STEP 1: Convert Input(s) to Base Unit
Maximum Possible S/N Ratio: 7 --> No Conversion Required
Actual S/N ratio at Output: 3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
F = S/N/S/Nout --> 7/3
Evaluating ... ...
F = 2.33333333333333
STEP 3: Convert Result to Output's Unit
2.33333333333333 Decibel --> No Conversion Required
FINAL ANSWER
2.33333333333333 Decibel <-- noise figure of amplifier

What do you mean by Base Station Subsystem?

It consists of one or more BTS and BSC. Each BTS is related to one cell which includes an antenna, a video trans-receiver, and a link to BSC. BSC controls multiple BTS units, manages the handoffs of the mobiles, and controls the paging.

How to Calculate Noise Figure?

Noise Figure calculator uses noise_fig_amplifier = Maximum Possible S/N Ratio/Actual S/N ratio at Output to calculate the noise figure of amplifier, The Noise Figure formula is defined as the noise figure is the difference in decibels (dB) between the noise output of the actual receiver to the noise output of an “ideal” receiver with the same overall gain and bandwidth when the receivers are connected to matched sources at the standard noise temperature. noise figure of amplifier and is denoted by F symbol.

How to calculate Noise Figure using this online calculator? To use this online calculator for Noise Figure, enter Maximum Possible S/N Ratio (S/N) and Actual S/N ratio at Output (S/Nout) and hit the calculate button. Here is how the Noise Figure calculation can be explained with given input values -> 2.333333 = 7/3.

FAQ

What is Noise Figure?
The Noise Figure formula is defined as the noise figure is the difference in decibels (dB) between the noise output of the actual receiver to the noise output of an “ideal” receiver with the same overall gain and bandwidth when the receivers are connected to matched sources at the standard noise temperature and is represented as F = S/N/S/Nout or noise_fig_amplifier = Maximum Possible S/N Ratio/Actual S/N ratio at Output. Maximum Possible S/N Ratio is the S/N ratio and Actual S/N ratio at Output is the ratio at output.
