Magnitude Comparator. We will begin by designing a simple 1 bit and 2 bit comparators. Comparators are used in central processing units cpus and microcontrollers mcus.

If the input bits are x and y then the output bits are corresponding to one of the case x y x y or x y. It is one of the two types of digital comparator. A digital comparator s purpose is to compare numbers and represent their relationship with each other.
There are also discrete ics available for comparison of binary numbers.
F1 x y xy x ex nor y. In this project sn7485 ic is used which is a 4 bit magnitude comparator. A magnitude comparator is a digital comparator which has three output terminals one each for equality a b greater than a b and less than a b. There are also discrete ics available for comparison of binary numbers.
