The difference in time it takes a signal to travel down different pairs of wires within a single cable. Specifically, the difference between the fastest and slowest pairs. Measured in time, usually nanoseconds.
When an electromagnetic field interrupts or degrades the normal operation of a piece of electronic equipment or signal. Also known as radio frequency interference (RFI).
The measurement of crosstalk at the opposite end of a cable where a signal originates, minus the attenuation of a signal due to cable length.
The measurement of crosstalk at the opposite end of a cable from where a signal originates.
