Introduction Digital Comparator

A digital comparator compares two binary numbers. The result indicates which number is larger or if the numbers are identical. Any modern microprocessor contains a variety of comparators. But even in simple logic circuits they are useful building blocks.

Comparators are used everywhere, where certain conditions affect the result. Think of a counter which has reached a certain value. Also comparators are used in microprocessors to test jump conditions and comparators in computers help to control the communication.

Comparators can be set up by a combination of logic gates. Find out what different kind of comparators there are and how they are constructed.

Before you can start with your first comparator, you need to make a few preparations.
