Design of MUX Based Circuit for Half Adder and Half Subtractor

This study delves into crafting a circuit that seamlessly performs both half addition and half subtraction. Leveraging two 2:1 Multiplexers, an XOR gate, and NOT gates, the design achieves dual functionalities while optimizing component usage. A control signal dictates the operational mode, ensuring adaptability with a straightforward assembly of common components. While this integrated circuit offers a compact and versatile solution for fundamental arithmetic operations, it's primarily suited for single-bit tasks and necessitates an extra control signal.
