RE: what make coaxial cable impedances of 50 ohms and 75 ohms ?
Posted by Duster on January 18, 2017 at 13:54:35:
Yes, the term is "characteristic impedance", which is based on a sophisticated determination based on the relationship of the dielectric with the conductors, rather than an actual measurement of the conductors resistance.
