# LOGIC DIAGRAM OF 4 BIT COMPARATOR 4 BIT COMPARATOR - EasyEDA
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. This is shows circuit diagram for 4-BIT COMPARATOR
4 Bit Comparator Logic Diagram - Wiring Diagram Networks
4 bit comparator logic diagram. So does the nor gate. Logic circuit of a 2 bit comparator how to design a 4bit comparator. The expressions for outputs of 1 bit 2 bit 3 bit and 4 bit magnitude comparator are explained in this video. It can be used to compare two four bit words. The figure below shows the logic diagram of a 2 bit comparator using
4-bit magnitude comparator
PDF file4-bit magnitude comparator Rev. 3 — 20 April 2018 Product data sheet 1 General description The 74HC85; 74HCT85 is a 4-bit magnitude comparator that can be expanded to almost any length. They perform comparison of two 4-bit binary, BCD or other monotonic codes and present the three possible magnitude results at the outputs (QA>B, QA=B and QA<B).
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.
Magnitude Comparator and Digital Comparator : Types
3-bit-logic-diagram 4-bit Magnitude Comparator. A comparator that compares two binary numbers (each number having 4 bits) and produces three outputs based on the relative magnitudes of given binary bits is called a 4-bit magnitude comparator. The input bits can be termed as A = A3 A2 A1 A0 and B = B3 B2 B1 B0. The output is A> B in the cases of
Binary Comparators - Electronics
An equality comparator, such as that illustrated in Fig 4.3.1 is the simplest multi-bit logic comparator, and can be used for such circuits as electronic locks and security devices where a binary password consisting of multiple bits is input to the comparator to be compared with another preset word.
