An examination of design theory for shift-register sequence generators capable of creating nonrepeating sequences longer than those obtained by the classical linear or nonlinear shift-register sequence generators. This capability is achieved by cyclically modifying the effective connections in the feedback loop. The technique described is particularly suitable for forming shift-register sequence generators out of passive elements, such as acoustical wire delay lines, and thus represents another step toward devices that yield maximal-length sequences with a minimum of equipment.
