Comparators

Definition of comparator : a device for comparing something with a similar thing or with a standard measure.

What is a comparator used for?

A comparator consists of a specialized high-gain differential amplifier. They are commonly used in devices that measure and digitize analog signals, such as analog-to-digital converters (ADCs), as well as relaxation oscillators.

What is a comparator in data?

A comparator compares two or more inputs using one, or a number of different comparisons.

Where are comparator circuits used?

Generally, comparators are used in the devices such as relaxation oscillators, analog to digital converters (ADCs), and also in the devices that are used to measure analog signals. The comparators consist of high-gain differential amplifiers and we can use an op-amp as a comparator circuit.

What is type of comparator?

Types of Comparators: Mechanical comparators 2. Optical comparators 3. Electrical & Electronic comparators 4. Pneumatic comparators 5.

Which one is a basic comparator?

Which one is a basic comparator? Explanation: Generally, an XNOR outputs high for even number of 1s or all 0s and outputs low for otherwise. Thus, an XNOR gate is a basic comparator, because its output is “1” only if its two input bits are equal.

What are the advantages of comparator?

Advantages of Electrical Comparator: Vibrations are reduced due to least weight of mechanical. It consists of less moving parts. By AC supply the friction errors are reduced. For measuring units the indicating instrument can be held at remote locations.

Which comparator is used to measure?

Detailed Solution. A comparator is an indirect type of instrument with the help of which an unknown dimension of a workpiece is compared with a working standard (usually slip gauges) and difference in dimension is measured.

What can a comparator detect?

-Comparators can also detect the following: Detect if a container block (chest, furnace, hopper minecart, etc) has an item in it. Unstackable items give the signal strength of a full stack of stackable items. Items which stack to 16 output the signal strength of four 64-stack items for every 16 stack item.

What is the difference between comparator and compare?

1) Comparable provides a single sorting sequence. In other words, we can sort the collection on the basis of a single element such as id, name, and price. The Comparator provides multiple sorting sequences. In other words, we can sort the collection on the basis of multiple elements such as id, name, and price etc.

What are comparator instruments?

It indicates difference in measurement between the component and working standard/ master settings. So, comparator is a precision instrument used to compare the measurement of unknown (part under test) with a known working standard.

What are different parts of comparator?

An electrical comparator consists of a base a stand, power unit, measuring unit, indication unit and amplification unit. In this comparator, the measuring contact movement is changed into an electrical signal and then this signal is recorded by a device that can be adjusted in terms of plunger movement.

What is voltage comparator?

A voltage comparator is an electronic device that compares an input voltage with a known reference voltage and changes its output state depending on the whether the input was above or below the reference.

What is 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.

What is a 3 bit comparator?

A comparator that compares two binary numbers (each number having 3 bits) and produces three outputs based on the relative magnitudes of given binary bits is called a 3-bit magnitude comparator. 3-bit magnitude. The equal functions are A0 = B0, A1= B1, A2 = B2.

What is the other name of comparator?

benchmark, comparable, reference.

What is a 2 bit comparator?

2) 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 analog comparator?

An analog, or magnitude, comparator is a device which has two analog inputs, like an operational amplifier, and one output which is assumed to have only two states, generally compatible with the input of one of the logic circuit families.

Which gate is used for comparator?

Note: An XNOR gate is a basic comparator, because its output is "1" only if its two input bits are equal. The analog equivalent of digital comparator is the voltage comparator.

What are the limitations of comparator?

The amplitude of the input signal is usually much larger than the linear range of the input amplifier stages. In this way a limitation of signals for the individual amplifier stages occurs. This amplitude limitation results in variations of the delay times of the zero crossings of the differential stages.
