"Swing" phenomenon Let's sum up two equal numbers 5 + 5 represented in the ternary mirror-symmetrical number system: It follows from this example that we have found the special addition case called the To eliminate the "swing"-phenomenon one may use the following effective "technical" method. Let's delay the input signals of the single-digit adders with odd indices ( Let's demonstrate the above-considered method for the preceding example of adding 5+5: The first step of the mirror-symmetrical addition is the carry formation from all the digits with the even indices (0, 2, -2). The adders of all digits with the odd indices (1, 3, -1, -3) do not operate at the first step. The second step is the addition of all carries arising at the first step with the ternary variables of the digits with the odd indices. |
