### where is the 75ohm part of digital rca's?

Posted:

**24 Nov 2016, 23:51**i just purchased a '75ohm digital" cable for an a/d converter.

If i measure the resistance from tip to tip its close to 0 ohms, from ground to ground its close to 0 ohms, from ground to tip its open circuit.

the cable is clearly marked "75 ohm digital" - can anybody explain to me what that actually means?

**edit i think i get it now, its the impedance not the resistance thats 75 ohm, info here ..
