LOGIC DESIGN FOR TRISTABLE DEVICES
JOSEPH A. KRUPINSKI · 1962
The development of a semiconductor device which exhibits three stable states of operation has prompted this thesis on ternary logic and its applications. A characteristic curve for the tristable device, called a TRINARY, is hypothesised and an equation determined which approximates the expected curve. The merits of the ternary system over binary are enumerated. The mathematics of a ternary number system is discussed and a method of converting between radix 3 and other number systems is presented. Some basic circuits of a ternary computer are presented and examples are given of a number of ternary circuits developed by others.
