What is magnitude comparator design a logic circuit for a 4 bit magnitude comparator and explain it?

What is magnitude comparator design a logic circuit for a 4 bit magnitude comparator and explain it?

4-Bit Magnitude Comparator – 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.

What is a logic comparator?

Logic comparators are the workhorse components of modern digital electronics and logic design. A logic comparator is made by two AND gates, Two inverter/NOT gates, and one NOR gate to be. It takes two inputs and compare the two inputs and produce an output, based on the condition or values of the two inputs.

What is magnitude comparator explain?

Magnitude Comparator are digital circuits which have two ports which accept and have three single bit outputs. It is used to comparing individual bits, multi-bit comparators can be constructed to compare whole BCD words to produce an output if one word is larger, equal to or less than the other.

What is magnitude comparator design a 3-bit magnitude comparator?

3-BIT MAGNITUDE COMPARATOR: A comparator which compare 2 binary numbers having 3-bits and produce the resultant of 3 outputs on the basis of magnitude of given binary numbers is called 3-bit magnitude comparator.

What are the two types of logic comparators?

There are two basic types of digital comparators: identity comparators and magnitude comparators. Identity comparators indicate whether two inputs are equal. Magnitude comparators indicate whether two inputs are equal and, if they are not, which input is larger or smaller.

What is a 8 bit comparator?

An 8-bit comparator compares the two 8-bit numbers by cascading of two 4-bit comparators. The circuit connection of this comparator is shown below in which the lower order comparator AB outputs are connected to the respective cascade inputs of the higher-order comparator.

Which logic is used in single bit digital comparator?

Exclusive-NOR gates
Digital comparators actually use Exclusive-NOR gates within their design for comparing their respective pairs of bits.

How do you draw logic circuit diagram?

The following is a systematic procedure to design a logic circuit:

1. Deduct the truth table from the human-readable specification.
2. Transfer the truth table into a Karnaugh map in order to simplify the function (if possible).
3. Deduct the circuit and draw the gate diagram (and the wired-circuit if required).

How does a 2-bit magnitude 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.

What is a simple 1-bit magnitude comparator?

A simple 1-bit magnitude comparator is shown in Fig 4.3.2. Gate 1 produces the function A>B and gate 3 gives A

What is the output state of a multi bit comparator?

If number A is greater than B than “greater than” output will produce HIGH state”1”. If A is less than or equal to B than “greater than” output will produce LOW state “0”. This is the basic unit of a multi bit comparator which compares a single binary bit and produces output according to those bits.

How do you design a 2-bit comparator in Equation 1?

Equation 1,2 and 3 also shows that the terms used in these equations are the product of the output of single bit comparators. 2-bit comparator design is discussed below. If we want to design 2-bit comparator all we have to do is put “n=2“ in‘n bits comparator’ equations.

How does an 8-bit comparator compare two numbers?

An 8-bit comparator compares the two 8-bit numbers by cascading of two 4-bit comparators. The circuit connection of this comparator is shown below in which the lower order comparator A B outputs are connected to the respective cascade inputs of the higher order comparator.
