Relationship between SNR and shielding effectiveness

[e0ne199]

Hello everyone, I have a question regarding shielding effectiveness and how it relates to SNR. Do you know what equation should be used to calculate SNR based on shielding effectiveness? Let's say the shield is an aluminum foil made into a dome covering transmitter and receiver inside. A general equation is really ok for me, as long as it is understandable. Your answer is really appreciated, thx before.

I don't think that is a question with an easy answer
Are you only considering "noise" due to interference? If so, what is the spectra?
How are you quantifying "shielding efficiency"? The attenuation in dB?

At the very least you need to split the question into two, i.e. calculate the shielding efficiency first, and then consider what that means for your SNR.
Generally speaking, this is not trivial.

shielding effectiveness and how it relates to SNR

Are you familiar with how to calculate SNR (for a particular modulation scheme and type of noise) based on the channel noise?
