Decimal-base binary logic (DBBL) adders and registers

This paper discusses a new type of base n adder and storage register. This new type of logic is called n-base binary logic , or NBBL. The NBBL system is compared and contrasted with the Post base n system (a type of n-valued logic), the binary-coded base n system, and the straight binary system. The main purpose of this paper is to show that a decimal, or base 10, system can have some important inherent advantages over a binary system, such as greater daily operational efficiency. Furthermore, it is shown that a decimal-base binary logic system, or DBBL system, has inherent advantages over the Post and binary-coded decimal systems. A cost analysis of the DBBL system relative to the straight binary system is performed and several circuit realizations for general NBBL adders and storage registers are shown. Two of the storage register realizations are SCR models that the author has actually built and thoroughly tested --Abstract, page ii
