I just need an elementary knowledge about TLs (for the tym being)....so i dont think the impedance chart is necesary at ths point of tym....so u need not lose sleep over it....
I have certain doubts regarding parallel wire lines...
1.Are parallel wire lines shielded????If they arent,wont the EM fields generated around them radiate into space and possibly interfere with other EM signals???
2.What are the advantages of using twisted pairs over parallel wire lines???
