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

Digital Comparator and Magnitude Comparator
The figure below shows the logic diagram of a 2-bit comparator using basic logic gates. It is also possible to construct this comparator by cascading of two 1-bit comparators. Back to top. 4-Bit Comparator. It can be used to compare two four-bit words. The two 4-bit numbers are A = A3 A2 A1 A0 and B3 B2 B1 B0 where A3 and B3 are the most
MC14585B - 4-Bit Magnitude Comparator
PDF file4-Bit Magnitude Comparator The MC14585B 4−Bit Magnitude Comparator is constructed with complementary MOS (CMOS) enhancement mode devices. The circuit has eight comparing inputs (A3, B3, A2, B2, A1, B1, A0, B0), three cascading inputs (A < B, A = B, and A > B), and three outputs (A < B, A = B, and A > B). This device compares two 4−bit words
Equality Comparators using Logic Gates | 101 Computing
4-bit Equality Comparator. Two binary inputs are equal if all their bits are equal. We can therefore design a multi-bit equality comparator by combining several XNOR gates together to compare each bit of both inputs. For instance, here is the logic gate diagram of a 4-bit equality comparator:
Project Report for COEN6511: ASIC Design
PDF fileFigure 2.5 Optimized logic diagram for a 4_bit comparator Seeing from the above diagram, we can use 11 gates to implement the 4-Bit comparator beside the inverters. The kind of gates includes XOR, AND, NOR. 4 gates of XOR are the same. 5 gates of AND have different number of inputs, but the principle of layout is the same. So does the NOR gate.
