Comparator

• An Electronics Device which converts two Analog Signals into one Digital Signal is Known as Comparator.

• It is a Device used in Digital Logic Design That Compares two characteristics like voltage and Current and Gives output in form of a Digital Signal.

Example Of Comparator

• An XNOR Gate is an Example of Comparator.

• Two Electric Signals are compared in XNOR . If the Positive Side signal is high then 1 is Obtained On output Where as if Negative side Signal is High 0 is obtained.

Types Of Comparator

• There Are two main Types of comparator;• Identity Comparator• Magnitude Comparator

Identity Comparator:The comparator Having only one Output Terminal is known as Identity Comparator.

Magnitude Comparator:A Digital Comparator Having Three Output Terminals for different Conditions is Called Magnitude Comparator.

Identity Comparator

• You want to compare two binary numbers and know if they are identical?

• Look at the truth table. The result x=y can only be equal to 1 if the inputs x and y are identical.

Odd Prime Number Detector

• The Circuit which gives odd Prime minterm Or it is the method where minterms are compared to eliminate the single variable.

• The Circuits that detects Odd prime number between 0 – 9 are considered earlier.

• Now the Circuit are improved by making 5bits system which can detect Odd Prime number Between 0 - 31

Quine-McCluskey method

• The Quine-McCluskey method can be used to simplify 5 variables Boolean expression represented in canonical form.

• The Quine–McCluskey algorithm or the method of prime implicate is a technique which is functionally identical to Karnaugh mapping, but the tabular form makes it more efficient for use in computer algorithms.
