Crosstalk

Crosstalk

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.
