The full subtractor can be implemented using ___________
A. Two XOR and an OR gates
B. Two half subtractors and an OR gate
C. Two multiplexers and an AND gate
D. Two comparators and an AND gate
Answer:B
The full subtractor can be implemented using ___________
A. Two XOR and an OR gates B. Two half subtractors and an OR gate C. Two multiplexers and an AND gate D. Two comparators and an AND gate
Explanation: A full subtractor has 3 input bits and two outputs bits BORROW and DIFFERENCE. The full subtractor can be implemented using two half subtractors and an OR gate.
