Relationship between SNR and shielding effectiveness

AI Thread 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.

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

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
