Ethernet transmission is broadband not tuned like a radio but the same equations as presented in the article hold across most of the bandwidth (where the skin effect holds). Actually, I am not sure whether the article is referring to tuned or broadband communication but in a sense it is irrelevant because practically, a large proportion of the energy transmitted in a modern broadband system is in the skin effect domain. If this wasn't the case, the system would be highly inefficient in the use of available bandwidth.
- tyingq 7y agoThe carrier frequency for 10b2 is 10Mhz.
- gugagore 7y agoIt's not a modulated signal encoding. There's no modulation, and so there's no carrier. The bandwidth is probably 20MHz, due to the Manchester encoding.
- tyingq 7y agoIt is Manchester encoding on a 10MHz clock signal. Perhaps carrier isn't quite the right word.
- gugagore 7y agoI take back by correction. Thanks, and sorry. Manchester encoding really is a form of phase modulation (BPSK). It makes sense to think of it as a 10MHz baseband signal modulated by a 10MHz carrier, and therefore having a 20Mhz bandwidth.
