Adders (electronics)

In electronics, an adder is a digital circuit that performs addition of binary numbers. Adders are fundamental building blocks in arithmetic logic units (ALUs) and are widely used in various computing systems, such as microprocessors and digital signal processors. There are several types of adders, each with different characteristics and purposes: 1. **Half Adder**: A basic adder that adds two single-bit binary numbers. It has two outputs: the sum (S) and the carry (C).
