Greetings!
We need to find the capacity of the channel. Google didn't come up with much. The only thing I found is
V = F * T * D - the volume of the channel, but the author calls it the capacity,
C = F ∙ log2 (1 + Pc / Psh) - the bandwidth.
In my case, F is known - the channel bandwidth, P_signal and P_noise.
Which formula will still give the correct answer?

I found the answer in the book "Electronic Communications Systems" by Wayne Tomasi on page 52. The heading is "Information Capacity".

Capacity?
Well, the electrical capacitance for example UTP cat5 is approximately 5600 picofarads - for every 100 meters long.
The capacity for the number of data transmission channels of the same utp-chi depends on the speed - for example, 10Mbps = 4, 100Mbps = 2, 1Gbps = 1 (10\100 in ideal conditions).
What do you specifically want to know? Preferably without wording from Soviet textbooks.
