One conductor is ground and shielding while the signal is trans‐ mitted through the core. Unbalanced transmission is susceptible to electromagnetic interference, especially at low levels, such as microphone signals and when using long cables. RTA-31 spectrum analyser...

Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized. The result is a pure signal without any noise inter‐ ference.
