If a 74HC85 magnitude comparator has A=1000 and B=1011 on its inputs, the outputs are

(A>B) =0; (A<B) =1; (A=B) =0     .    

(A>B) =0; (A<B) =0; (A=B) =1

C,(A>B) =1; (A<B) =0; (A=B) =0   

(A>B) =1; (A<B) =0; (A=)B =1

Solution

A = A3A2A1A0 B= B3B2B1B0

A3=B3

A2=B2

A1<B1

So the outputs are (A>B) = 0 ; (A<B) = 1; (A=B) = 0
