1. An encoding method for a plurality of closely spaced electrical signal paths, the encoding method comprising: determining signal transition activity for each electrical signal path for a predetermined set of electrical impulses; grouping the electrical signal paths into a plurality of source windows, each source window comprising a portion of the electrical signal paths and each portion comprising adjacent electrical signal paths; and cross-connecting the source windows to a plurality of target windows based upon a base capacitance between each of the electrical signal paths and a ground plane layer, a coupling capacitance between each of the electrical signal paths and the signal transition activity.
