Functional stability conditions for logic devices of K- valued logic

For any input signal of logic elements (LE) which realize logical functions of
K
-valued logic to be converted into any output signal, it has been shown to be sufficient that the LE have
2(K- 1)
different input-output characteristics without equal values of the output signal at neighboring discrete values of input signals. Sufficient conditions for stable operation of both long closed and short logical chains of elements with characteristics under consideration are formulated.
