Calculation of SNR

[Shruti01]

How to calculate the SNR of received signal that contains both signal and noise. I have no information about the type of signal and noise been used.

 

[QDP2012]

I am not sure if you are asking for general info about SNR, or something more specific. Maybe this will help or at least be a starting point:

Wikipedia: Signal to Noise Ratio

It has some explanation of the calculations.

Hope this helps,

Calculate the SNR

SNR is calculated between signal and noise. It can be formulated as follows:-

SNR = Psignal/Pnoise = μ/σ

where
μ is the signal mean or expected value
σis the standard deviation of the noise

it is also derived formulated by,
( \mathrm{SNR} = \frac{P_\mathrm{signal}}{P_\mathrm{noise}}, )
it means,where P is average power. Both signal and noise power must be measured at the same or equivalent points in a system.
