Question: Derive the Boolean function of the carry - out for a 4 - bit carry - lookahead adder. Compare its delay with the Boolean function

Derive the Boolean function of the carry-out for a 4-bit carry-lookahead adder.
Compare its delay with the Boolean function that generates the carry out of 4-bit
ripple carry adder. Calculate the delay of the same paths when the adders are 8
bits. XOR: 2 ns AND/OR: 1 ns'
