Note that this paper does not mention balanced ternary and only presents tables, diagrams and results for unbalanced ternary with values 0, 1 and 2.
The Setun computer, mentioned in the introduction, however, used balanced ternary with values -1, 0 and 1. Balanced odd bases consist of digits centered around zero.
Could balanced ternary redeem it's position with logic cirtuits in mind?
