Abstract:
We study the connections between the Boolean functions with generalized filter taboo (a pattern which cannot appear in the output sequence of a filter generator) and classes of $k$-valued logic functions constructed from these Boolean functions by means of extension method. It is shown that generalized filter taboo of a Boolean function may correspond to the generalized filter taboo of $k$-valued logic function as well as to its generalized filter semitaboo (a pattern in the output sequence of a $k$-valued filter generator which restricts the sets of possible values of some elements in the input sequence).
