Depending on characteristics of the [[Analog signal|signal]] and [[Transmission line|transmission]] topology, previously transmitted symbols can affect the edge cross over time. This creates a [[Probabilityprobability distribution]] for the timing of the signal edge, which is usually recorded in a [[Probability density function|PDF]].
 
DDJ's [[Probability density function|PDF]] is always a series of [[Pulse (signal processing)|pulses]] at the locations where a specific bit pattern experiences a [[Crossover distortion|cross over]]. Therefore, in order to get an accurate measure of the DDJ in a particular system, a large number of bit patterns must be analyzed (often just a [[PRBS]]) unless an [[analytical solution]] can be found.
