Implement Full Subtractor Using Demux

ices are primarily used for data routing, their ability to selectively activate outputs depending on input combinations can be harnessed to implement specific logic functions, including arithmetic circuits like the full subtractor. Why Use Demux for Implementing a F

Design Half Subtractor Using Nand Gate

output of step 1. 2. Similarly, NAND B with the output of step 1. 3. Finally, NAND the results of steps 2 and 3 to produce A ⊕ B. 4. This implementation uses four NAND gates to replicate the XOR behavior perfectly. Step-by-Step Implementation of XOR Using NAND
