In the negabinary system an i?bit binary integer, N, is expressed using positional notation as:
This is the same as conventional natural 8421 binary weighted numbers, except that alternate positions have
the additional weighting +1 and ?1. For example, 1101 = (?1 × 1 × 8) + (+1 × 1 × 4) + (?1 × 0 × 2) + (+1 × 1 × 1) = ?8
+ 4 + 1 = ?3. The following 4?bit numbers are represented in negabinary form. Convert them into their decimal
equivalents.
a. 0000
