## Question:

Design one bit of a digital circuit that performs the four logic operations of exclusive- OR, exclusive- NOR, NOR, and NAND on register operands A and B with the result to be loaded into register A. Use two selection variables.

**(a) **Using a Karnaugh map, design minimum logic for one typical stage, and show the logic diagram.

**(b) **Repeat (a), trying different assignments of the selection codes to the four operations to see whether the logic for the stage can be simpliied further.
