What is N bit comparator?

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.

Which of the following is true for IC comparator circuits?

Which of the following is true for IC comparator circuits? All comparators have outputs for indicating AB, and A=B. Comparators can compare only 2 bits at a time. Comparators can compare only two values at a time.

What is a digital comparator circuit?

Definition: A Digital Comparator is a combinational logic circuit that is used for comparison of two binary values. Basically it generates the desired signal (either low or high) at the output when compares two digital values provided at its input.

Which gate is best used as comparator?

Exclusive-OR can be used as a basic comparator.

What is 2-bit digital comparator?

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 relationship between L e and g in 1 bit comparator?

So, the comparator produces three outputs as L, E and G corresponds to less than, equal and greater than comparisons. Comparators that have only one output terminal and produces the output either low or high are identity comparators.

Which logic is used in single bit digital comparator?

We logically design a circuit for which we will have two inputs one for A and another for B and have three output terminals, one for A > B condition, one for A = B condition and one for A < B condition. Digital comparators actually use Exclusive-NOR gates within their design forcomparing their respective pairs of bits.

How many types of digital comparators are?

Explanation: there are two main types of digital comparator available and these are: identity comparator & magnitude comparator.

What Cannot be combined into K map?

Q.	Which of the following combinations cannot be combined into K-map groups?
B.	corners in the same column
C.	diagonal corners
D.	overlappin g combinati ons
Answer» c. diagonal corners

What is the difference between combinational logic and sequential logic?

The combinational circuit is time-independent. The output it generates does not depend on any of its previous inputs. On the other hand, sequential circuits are the ones that depend on clock cycles. They depend entirely on the past as well as the present inputs for generating output.

What is a 8 bit comparator?

An 8-bit comparator compares the two 8-bit numbers by cascading of two 4-bit comparators. The circuit connection of this comparator is shown below in which the lower order comparator AB outputs are connected to the respective cascade inputs of the higher-order comparator.
