 Signed-digit representation

Signed-digit representation is a method used to encode numbers in a way that retains both their magnitude and sign, allowing for efficient arithmetic operations, particularly in digital electronics and computer systems. In this representation, each digit can take on multiple values, typically including both positive and negative values, as well as zero. ### Key Features: 1. **Digit Values**: In signed-digit systems, digits can be represented as: - Positive digits (e.g.
