sorry guys..i'm newbie..
may i know the method how to measure characteristic impedance of wire?
when I online searching,there have a easy method for low frequencies,
"measure the capacitance along the cable,C;then short the other end of the cable,measure the induce,L then Z0=sqrt(L/C)"
but how to measure the capacitance along the cable? is it any circuit can provide for reference ? thanks a lot !
