Relationship between SNR and shielding effectiveness

Click For Summary
Shielding effectiveness is crucial for understanding the signal-to-noise ratio (SNR) in communication systems. To calculate SNR based on shielding effectiveness, one must first determine the shielding efficiency, often expressed in decibels (dB). The relationship between shielding effectiveness and SNR is complex and typically requires consideration of the specific type of noise and modulation scheme involved. It is recommended to separate the calculations into two parts: first assessing shielding efficiency, then evaluating its impact on SNR. Overall, this topic involves nuanced calculations that are not straightforward.

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.
 
I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
