(a) 1

(b) 0

(c) A

(d) B

I got this question in unit test.

I'm obligated to ask this question of Magnitude Comparator in division Combinational Circuits of Digital Circuits

Answer 1

The correct answer is (a) 1

The explanation is: A comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. If A > B, it means that it satisfies one of the condition among three. Hence the output will be 1.
