but i ponder why there seems to be so many opposing /contradicting
views on same subjects and topics and i am not referring to just those here on the news groups if i get x people in a room ask about baluns or chokes 1/2 say one thing the other 1/2 say something else dunno it's strange in all that confusion obviously we all pick what we interpert and believe to be best but i hate when that happens It's real easy to get caught up the definitions. A transformer transforms impedance, voltage or current and often isolates but not necessarily. A choke uses the magnetic field created by the AC current through it to oppose that current. The wiki points out there are balanced and unbalanced signals. Webster says balanced and unbalanced lines. Someone posted that coax is in fact a balanced line. OK that can be oddly true, but it can be unbalanced by how you connect it. So it can be part application, part configuration, part common word usage that might not be purely accurate, and where you are focusing your attention. Still, it can be many prefer to be an expert and argue and make statements rather than ask the questions. I must confess after a project, I often let details slip by me unlike day to day operations that I can't get out of my head 30 years later. I can still align Micor and Motrac radios in my sleep step by step. The whole discussion could have all been on a roundtable net but then we wouldn't have the luxury of nit-picking and cussing each other out. |
