What is magnitude comparator circuit?

What is magnitude comparator circuit?

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.

How many OR gates are required for 4-bit magnitude comparator?

Optimized Logic diagram of 4-bit magnitude comparator: The type of gates includes XOR, AND, NOR. There are 4 XOR gates used with the same inputs. There are 5 gates of AND or NOR used with the different number of inputs but in both of them the principal of layout is same.

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 do you write a two bit comparator truth table?

2-Bit Comparator The first number A is designated as A = A1A0 and the second number is designated as B = B1B0. This comparator produces three outputs as G (G = 1 if A>B), E (E = 1, if A = B) and L (L = 1 if AThe truth table of this comparator is shown below which depicting various input and output states.

What is bit magnitude comparator?

1) 1-Bit Magnitude Comparator : 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.

How does magnitude comparator work?

A digital comparator or magnitude comparator is a hardware electronic device that takes two numbers as input in binary form and determines whether one number is greater than, less than or equal to the other number. Comparators are used in central processing units (CPUs) and microcontrollers (MCUs).

What is 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.

What is the main uses of magnitude comparator and identity comparator?

It is widely used in CPU, microcontroller, combinational and communication systems and is specially designed to compare the relative magnitudes of binary numbers. This comparison is used for testing whether one number represented by one binary word is greater than, equal, or less than the other number.

What are the logic conditions in comparator?

A comparator compares two or more inputs using one, or a number of different comparisons. when the given relationship(s) is true, an output signal is given (logic 0 or logic 1). Comparators are only modeled using the if statement with an else clause and no else – if clauses.

What is a comparator logic?

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. Two common types of digital comparators exist, an Identity.

Which is not the output of magnitude comparator?

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. In a digital comparator, only 3 outputs are possible (i.e. A = B, A >B, A < B). Other than this, the output will be 0.

Which is not an outcome of magnitude comparator?

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. In a digital comparator, only 3 outputs are possible (i.e. A = B, A > B, A < B). So, a – b is an incorrect option.

What is 2-bit magnitude comparator?

Why comparators is used what are its basic elements?

“A comparator is an indirect type of instrument with the help of which an unknown dimension of a component is compared with a known dimension of a standard component, usually slip gauges”. Comparators are used to find-out deviation of dimensions between a given component being checked and a known datum.

How many inputs and outputs are there in comparator?

A comparator is an electronic circuit, which compares the two inputs that are applied to it and produces an output. The output value of the comparator indicates which of the inputs is greater or lesser.
