摘要：An electrical system wherein the electrical conductive traces on the circuitboards are routed to achieve a balanced net to reduce noise caused by transmission line
reflections. A trace (202,216,248,274) is routed from the source terminal (200,214,236,260)of the net to a balanced junction (204,218,238,288) wherein if there are an odd number ofload terminals, or loads, the balanced junction is located at one of the loads (204,238).The remaining loads are grouped into branches wherein each branch includes an equalnumber of loads. A trace is routed between each of the loads of each branch to seriallyconnect the loads of each branch together, or, a trace is routed from a center one of thebranch loads to each of the remaining branch loads, forming subbranches. In an alternateembodiment, a balanced subbranch is developed. The balanced load is connected to apseudo-balanced load, which further receives an equal number of branches. The 3pseudo-balanced load is then connected to another pseudo-balanced load, which mayalso receive an equal number of branches. This pseudo-balanced load is connected to thesource. In another alternative, two balanced subbranches have their balanced loadsconnected to a central balanced load. This balanced load may receive even furthernumbers of equal branches. The balanced load is connected to the source.
