### Questions with Logic - Comparators

• ##### Ask: How does a 4 bit comparator work?

Answer: Binary comparators, also called digital comparators or logic comparators, are combinational logic circuits that are used for testing whether the value represented by one binary word is greater than, less than, or equal to the value represented by another binary word. Two basic types of comparator can be used.

• ##### Ask: How many types of digital comparators are?

Answer: 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 unit s (CPUs) and microcontrollers (MCUs).

• ##### Ask: What is basic comparator?

Answer: A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.

• ##### Ask: How many inputs are required for a digital comparator?

Answer: 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.
