Q1:

A magnitude comparator determines:

A A notequalto.gif B and if A alpha.gif B or A >> B

B
A almostequal.gif B and if A > B or A < b

C
A = B and if A > B or A < b

D
A identicalto.gif B and if A < b or a > B

ANS:C -

A = B and if A > B or A < b

A digital comparator or magnitude comparator is a hardware electronic device that takes two numbers as input in binary form and determines whether one number is greater than, less than or equal to the other number.
