draw the eye diagram you would expect to see should a digital signal be passed through a transmission line with a bandwidth limited to three times the maximum bit rate of the digital signal.
the answer is "Only f1 and f3 pass through"
My question is, what about f2 ?
Why does the answer to this question read f1 & f3 rather than f1 - f3 (including f2) ?
Thanks for any clarification.
fran1942 said:Hello, thanks for your help. I have tried thinking about this one, but I still can't understand why f2 is not mentioned in the answer to this question.
If you could please offer some further explanation that would be great.
Thank you.
An eye diagram is a graph that shows the signal quality of a digital communication system. It plots the amplitude (or voltage) of the signal over time and allows engineers to analyze the performance of the system by identifying different signal impairments.
An eye diagram is created by sampling the digital signal at regular intervals, usually with an oscilloscope, and plotting the results in a graph. The resulting shape resembles an "eye", hence the name.
An eye diagram provides information about the signal quality of a communication system, including the signal's amplitude, shape, and timing. It can reveal problems such as noise, distortion, and timing errors, which can affect the performance of the system.
An eye diagram is used in troubleshooting to identify and locate signal impairments in a communication system. By analyzing the shape and characteristics of the eye diagram, engineers can pinpoint the source of the problem and make necessary adjustments to improve the signal quality.
Using an eye diagram allows engineers to quickly and accurately assess the performance of a communication system. It provides a visual representation of the signal quality, making it easier to identify and troubleshoot problems. It also allows for better optimization of the system, leading to improved overall performance.
