Help! Is it true that by using the Ref Z in the typical bridge measuring circuit and getting a good match it follows that the Terminal Equipment's input impedance will be equal to the Ref Z ?
So, with regard to European CTR21, is the complex Reference Z equal to the telephone line impedance or does represent the complex conjugate so as to provide a power match when I design the TE's input impedance to provide a good return loss in the measuring bridge? (I do understand that the discrete components used in the Reference Z are probably an approximate model of the real world) Thanks, Alan Shaw Napco 1 631 842 9400
