Question 1: Write a note on COMPARATOR
A 2-bit Comparator circuit compares two 2-bit numbers A and B. The comparator circuit has three outputs. It sets the A>B output to 1 if A>B. It sets the A=B output to 1 if A=B and sets A<B output to 1 if A < B.
The output A>B is set to 1 when the input combinations are 01 00, 10 00, 10 01, 11 00, 11 01 and 11 10
The output A=B is set to 1 when the input combinations are 00 00, 01 01, 10 10 and 11 11
Answer:
COMPARATOR
A comparator circuit compares two numbers and sets one of its three outputs to 1 indicating the result of the comparison operation. A Comparator circuit has multiple inputs and three outputs.A 2-bit Comparator circuit compares two 2-bit numbers A and B. The comparator circuit has three outputs. It sets the A>B output to 1 if A>B.
