What is a 2-bit comparator?

## What is a 2-bit comparator?

A comparator used to compare two binary numbers each of two bits is called a 2-bit magnitude comparator. It consists of four inputs and three outputs to generate less than, equal to and greater than between two binary numbers.

### Which IC used in 2-bit comparator?

These comparators can compare 2-bit, 4-bit and 8-bit numbers depending on the application requirement. These are available in TTL as well as CMOS logic family ICs and some of these ICs include IC 7485 (4-bit comparator), IC 4585 (4-bit comparator in CMOS family) and IC 74AS885 (8-bit comparator).

What are the application of 1 bit & 2-bit comparator?

These are used in control applications in which the binary numbers representing physical variables such as temperature, position, etc. are compared with a reference value. Comparators are also used as process controllers and for Servo motor control. Used in password verification and biometric applications.

What is comparator design & implement a 2-bit comparator using logic gates?

Comparator – Designing 1-bit, 2-bit and 4-bit comparators using logic gates. A Comparator is a combinational circuit that gives output in terms of A>B, A. This is entirely expected from the name. A digital comparator’s purpose is to compare numbers and represent their relationship with each other.

## What are the applications of 1 bit and 2-bit comparator?

### What are the outputs of comparator?

The comparator output only takes one of two possible states: “high state or low state”. In order to explain the circuit operation, voltage vA is assumed at its high state (assuming the opposite is also possible, in order to reach the same result). Operational amplifiers are supplied at ± Vcc.

How do you make a 4-bit comparator?

Algorithm of 4-bit comparator: Now let us consider two numbers, A and B, with four digits each. Then, write the coefficients of the numbers in descending order. It comprises of eight inputs each for two 4- bit numbers to generate three outputs that are less than, equal to and greater than in between two binary numbers.

What is the IC number of 2 input NAND gate?

Usage/Application Electronics
Part Number 74HC00
Temperature Up to 70 DegreeC
Number Of Pins 14

## How does a 2-bit comparator work?

A 2-bit comparator compares two binary numbers, each of two bits and produces their relation such as one number is equal or greater than or less than the other. The figure below shows the block diagram of a two-bit comparator which has four inputs and three outputs.

### What is FSM in VHDL?

A finite-state machine (FSM) is a mechanism whose output is dependent not only on the current state of the input, but also on past input and output values.

Does FSM have memory?

FSM doesn’t have memory, It can’t remember the things unlike Push Down Automata (i.e nothing but a FSM with Memory). Anything which require memory can’t accepted by FSM.

What will the output of two 1 bit comparator having a and b as input *?

Explanation: A comparator is a combinational circuit that takes two numbers as input in binary form and results whether one input is greater, lesser or equal to the other input. If A > B, it means that it satisfies one of the condition among three. Hence the output will be 1.
