This paper presents and first scientifically substantiates the generalized theory of binomial number systems (BNS) method their formation for reliable digital signal processing (DSP), transmission, data storage. The is obtained based on general positional (PNS) with conditions functions converting BNS a binary alphabet, also allowing to generate matrix BNS, linear-cyclic, multivalued systems. G...
