Abstract
The linear separability concepts are applied in order to give either necessary or sufficient conditions for realizability by exactlyn threshold elements of a given coded cycle set of an autonomous nonsingular sequential circuit, specified byn boolean functions. Two main classes are obtained, the self-dual and the pure majority classes corresponding respectively to a necessary and to a sufficient condition. Also “necklace” circuits are described which exhibit remarkable properties. The number ofrealizable, non singular autonomons circuits are enumerated up ton=5, and one investigates also the capability of circuits ofn threshold elements to perform a state cycle of length2 n. Finally, in Appendix I, a constructive method to generate a non singular transition table is given.
