Hello, I have just started reading some telecommunications basic concepts. I have a question regarding the following phrase: "when considering that transmission lines are used in transmitting AC signals: R << ωL G << ωC In high frequency applications the R is so much smaller than the xL that R can be ignored. The G is so much smaller than xC that G can be ignored......" Can someone please tell me what the ωL and ωC terms mean ? What significance/meaning does the ω symbol have ? Thanks kindly for any help.
