# 4 BIT COMPARATOR LOGIC DIAGRAM AND TRUTH TABLE

Comparator - Designing 1-bit, 2-bit and 4-bit comparators
The logic circuit of a 2-bit comparator How to design a 4–bit comparator? The truth table for a 4-bit comparator would have 4^4 = 256 rows. So we will do things a bit differently here. We will compare each bit of the two 4-bit numbers, and based on that comparison and the weight of their positions, we will draft a truth table.
Magnitude Comparator in Digital Logic - GeeksforGeeks
A comparator used to compare two binary numbers each of four bits is called a 4-bit magnitude comparator. It consists of eight inputs each for two four bit numbers and three outputs to generate less than, equal to and greater than between two binary numbers. In a 4-bit comparator the condition of A>B can be possible in the following four cases:

PDF file2 Logic design for 4-bit comparator 2.1 logic design procedure Magnitude comparator is a combinational circuit that compares two numbers and determines their relative magnitude. A comparator is shown as Figure 2.1. The output of comparator is usually 3 binary variables indicating: A>B A=B A<B A>B A=B A<B Comparator A B
