What is a 2-bit magnitude comparator?
2-Bit Magnitude 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.
How many types of magnitude comparator are there?
Types of Magnitude Comparators: 1-bit magnitude comparator. 2-bit magnitude comparator. 3-bit magnitude comparator. 4-bit magnitude comparator.
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 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 & 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.
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 applications of 1 bit and 2-bit comparator?
What is 2-bit magnitude comparator design?
ABSTRACT: 2-bit magnitude comparator design using different logic styles is proposed in this brief. Comparison is most basic arithmetic operation that determines if one number is greater than, equal to, or less than the other number. Comparator is most fundamental component that performs comparison operation.
How to verify the truth table of a magnitude digital comparator?
Verify the truth table of one bit and two bit comparator using logic gates. A magnitude digital comparator is a combinational circuit that compares two digital or binary numbers in order to find out whether one binary number is equal, less than or greater than the other binary number.
Which comparator is used to compare two bits?
A comparator used to compare two bits is called a single bit comparator. It consists of two inputs each for two single bit numbers and three outputs to generate less than, equal to and greater than between two binary numbers. The truth table for a 1-bit comparator is given below:
What is the truth table for a 1-bit comparator?
The truth table for a 1-bit comparator is given below: From the above truth table logical expressions for each output can be expressed as follows: A>B: AB’ A
