Q1:

The binary numbers A = 1100 and B = 1001 are applied to the inputs of a comparator. What are the output levels?

A A > B = 1, A < B = 0, A < B = 1

B A > B = 0, A < B = 1, A = B = 0

C A > B = 1, A < B = 0, A = B = 0

D A > B = 0, A < B = 1, A = B = 1

ANS:C - A > B = 1, A < B = 0, A = B = 0

It's a bitwise comparison so A=B=1 , A>B=1,A<B=0.
according to my knowledge,
A=1101
B=1001.

1st-row A=B, 2nd-row A>B, 3rd-row A=B, 4th-row A=B.

E is equal, G is greater.
