On implementation of some systems of elementary conjunctions in the class of separating contact circuits

Abstract We show that the system of elementary conjunctions Ωn,2k=K0,…,K2k−1 $ \Omega_{n,2^k} = {K_0,\ldots,K_{2^{k} -1}} $ such that each conjunction depends essentially on n variables and corresponds to some codeword of a linear (n, k)-code can be implemented by a separating contact circuit of complexity at most 2k+1 +4k(n − k) − 2. We also show that if a contact (1, 2k)-terminal network is separating and implements the system of elementary conjunctions Ωn,2k $ \Omega_{n,2^k} $ , then the number of contacts in it is at least 2k+1 − 2.
