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.

Which is a 4-bit magnitude comparator IC?

The 4-bit comparator is mostly available in IC form and common type of this IC is 7485. This IC can be used to compare two 4-bit binary words by grounding I (A>B), I (A

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 are the outputs of a 7485 four bit magnitude comparator?

Correct Answer: Quad two-input multiplexer.

How does a 4-bit comparator work?

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.

How many entries will be in the truth table of a 4 input NAND gate?

The Experiment So, a 4-input AND gate has 16 possible combinations, 5 inputs would be 32 outputs, and so on.

What is a 4-bit comparator?

What is meant by multiplexer explain with diagram and truth table the operation of 4 to 1 line multiplexer?

A 4-to-1 multiplexer consists four data input lines as D0 to D3, two select lines as S0 and S1 and a single output line Y. The select lines S0 and S1 select one of the four input lines to connect the output line.

How many types of magnitude comparators are there?

Types of Magnitude Comparators: 1-bit magnitude comparator. 2-bit magnitude comparator. 3-bit magnitude comparator. 4-bit magnitude comparator.

What is the Boolean expression for a four input OR gate?

The Boolean expression of OR gate is Y = A + B, read as Y equals A ‘OR’ B.

How many entries will be in the truth table of a 4 input NAND gate * A 6 B 8 C 32 D 16?

For a input AND gate, there are different input combinations so the truth table will have 16 entries.

What is a 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. In a 4-bit comparator the condition of A>B can be possible in the following four cases:

How many inputs and outputs does a 4-bit comparator have?

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. In a 4-bit comparator the condition of A>B can be possible in the following four cases: Similarly the condition for A

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 4-bit comparator?

The truth table for a 4-bit comparator would have 4^4 = 256 rows. So we will do things a bit differently here. We will compare each bit of the two 4-bit numbers, and based on that comparison and the weight of their positions, we will draft a truth table. Now let’s derive the equations for the three outputs.
