Crosstalk is the amount of signal from one active channel that appears on another active channel. Crosstalk is specified in dB of transmission, according to one of the following equations:

Crosstalk (dB) = 10 log (Pout / Psource)

Crosstalk (dB) = 20 log (Vout / Vsource)

The following figures illustrate crosstalk. All channels are assumed to be appropriately terminated.
