Different types of substractors

Answer 1

Substractors are digital circuits used to perform subtraction operations. The main types include half subtractors, which subtract two single-bit binary numbers and produce a difference and a borrow output, and full subtractors, which handle the subtraction of three bits (including a borrow from a previous operation). There are also multi-bit subtractors, which can subtract larger binary numbers using cascaded full subtractors. These circuits are fundamental components in arithmetic logic units (ALUs) within processors.
