Twisted Pair – Part of a Balanced Interface


• "A balanced circuit is a two-conductor circuit in which both conductors and all circuits connected to them have the same impedance with respect to ground and all other conductors." - Henry Ott, Noise Reduction Techniques in Electronic Systems, 2nd Ed. page 116

• Defense against unwanted noise

• Rejection of Common-Mode noise


Unbalanced Interface


• Center conductor and shield

– Impedance between the signal conductor (center conductor) and shield (return conductor) is not the same – “unbalanced”

– No protection against interfering noise

– Cable length limitations

– Clues

• Consumer gear

• Phono (RCA) connectors
