How a hum eliminator works: 60 cycle hum - ground loop current - only flows on the shield of a video cable. This current will produce a magnetic field in the iron core of the hum eliminator and create an inductor, or choke. The high impedance of this choke - in the ground path - effectively eliminates the 60 cycle hum from passing through the unit. The video signal, on the center conductor, is shielded from this impedance - by the cable's shield - and passes through the unit unaffected. This is true whether the signals are analog or digital.
