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.
How many types of magnitude comparator are there?
This comparison is used for testing whether one number represented by one binary word is greater than, equal, or less than the other number. There are two main types of digital comparators available: Identity comparator and Magnitude comparator.
What is magnitude comparator explain 1-bit magnitude comparator?
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.
What is 8bit comparator magnitude?
An 8-bit magnitude comparator compares the two 8-bit values and produce a 1-bit flag as result, which indicates that the first value is either greater than or less than or equal to the second value.
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 are types of comparator?
Types of Comparators
- Mechanical Comparator.
- Mechanical-Optical Comparator.
- Reed Type Comparator.
- Electrical-Electronic Comparator.
- Pneumatic Comparator.
What are the two types of comparator?
Types of Comparators: Mechanical comparators 2. Optical comparators 3. Electrical & Electronic comparators 4. Pneumatic comparators 5.
What is comparator and its type?
Comparators are classified into various kinds, such as electronic, electrical, mechanical, optical, sigma, digital and pneumatic comparators, these are used in various applications. When the i/p signal is sampled, then this signal is applied to multiple comparators to convert the digital form from analog.
Which type of comparator is more accurate?
Comparators can be Mechanical or Electrical by the mean used for comparison. The dial indicator or the dial gauge is one of the simplest and the most widely used Mechanical comparator. Electronic gauges are more accurate and reliable than mechanical, which has made them the preferred choice in many applications.
How is a 2 bit magnitude comparator used?
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. The truth table for a 2-bit comparator is given below:
What do you call a 4 bit 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 inputs does a Karnaugh magnitude comparator have?
A three bit magnitude comparator has two inputs A 2 A 1 A 0 and B 2 B 1 B 0 An integrated circuit magnitude comparator (7485) would actually have four inputs, But, the Karnaugh map below needs to be kept to a reasonable size. We will only solve for the A>B output.
Which is the product of single bit comparator equations?
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.
