A comparator is a combinational circuit that compares two binary values and determines their relationship: greater than (A > B), less than (A < B), or equal (A = B). It is a fundamental building block in digital systems, used in processors, arithmetic units, and decision-making circuits.
The binary or digital comparator can be constructed using standard AND, NOR and NOT gates to compare the digital signals present at their input terminals and produce an output depending upon the condition of those inputs.
Binary comparators are logic gates circuit used to compare two binary inputs. There are two types of binary comparators: Equality Comparators are used to check if the two binary inputs (A and B) are equal or not.
