Crosstalk

the effect whereby a signal on one conductor will be transposed to an adjacent conductor due to mutual capacitance and mutual inductance. It is usually measured as a percentage of the applied voltage; for example, if a 1 volt peak to peak signal is transmitted on one line, a nearby line may show a 0.1 volt peak to peak signal; this corresponds to 10% crosstalk. The frequency or risetime of the signal must be specified. In general, crosstalk will increase with higher frequencies or faster risetimes. Measurements are usually made with one or more active lines and one quiet or victim line. The active lines are the conductors that are driven by a signal; the quiet or victim line is the conductor being affected by the driven lines.
