Two cables data transmission

AI Thread Summary
Connecting two cables with different bandwidths and signal-to-noise ratios (SNR) raises questions about compatibility and performance. While it's theoretically possible to utilize the lower SNR of the second cable, practical implementation may require a frequency translator to harmonize the bandwidths. The SNR can vary along the length of a cable and is influenced by the frequency of data transmission. Additionally, without specific details on the cables' limitations and inherent noise sources, it's difficult to determine the overall effectiveness of combining them. Ultimately, if the SNR of the first cable is already adequate, the benefits of paralleling the cables may be minimal.

okay guys i have a small problem relating to network data transmission

i have two cables

cable 1 :- Bandwidth = B1 and SNR = S1
cable 2 :- Bandwidth = B2 and SNR = S2

Assume that B2 > B1

Cant i connect these two cables together and take advantage of lower SNR ratio requirements of the cable 2 ?

Will i need some sort of frequency translator device to match the two difference bandwidth capabilities of the two wires ?

signal to noise ratio

Also,

Is the signal to noise ratio of a data transmission cable be constant throughout the cable or does it change in a undefined manner ?

Also does it have a relationship with the frequency of data transmission ?

What is the context of the question? What kind of channels are we talking about? What is limiting the BW of each cable? And how are you defining the SNR? Is there an inherent noise source in each? What are the TX signal levels? What is the attenuation? What is the quiet line SNR at the RX amp?

(and is this schoolwork?)
 
Given B2 > B1, how do you know S2 > S1? Is the needed bandwidth greater than B1 or the needed SNR greater than S1? In general, without knowing the details of your problem, if your SNR is better than marginal, the amount of improvement you would get by paralleling cables would be negligible.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
