From the logic gate diagram given below:
(a)[4.0]
Derive Boolean expression for X(A, B, C) and draw the truth table.
(b)[1.0]
Write the canonical expression for SUM and CARRY of a half adder.
Answer
Answer (b)
AIFor a half adder with inputs A, B: SUM = A'B + AB' (canonical SOP, equivalent to A XOR B). CARRY = A.B (canonical AND term).
