5. Carry-lookahead adder: (a) [6%] Give the Boolean function for the carry

5. Carry-lookahead adder: (a) [6%] Give the Boolean function for the carry generate and the carry propagate, respectively, in the carry-lookahead adder design. (b) [6%] If we replace the AND & OR gates between adjacent group with a MUX, the circuit also works. Why? Does using the MUX make the adder faster, slower, or about the same speed? Why?
