Comparators belong to the group of arithmetic logic units. Other arithmetic logic units, such as adders, compute binary numbers. However a digital comparator compares binary numbers.

A distinction is made between two types of comparators.
The **Identity Comparator** compares two numbers
and determines whether the numbers are identical.
A **Magnitude Comparator** compares two numbers
and indicates which number is bigger.

In this **first part** you learn how to set up
the different comparators.
In **6 experiments** you build comparators as a combination
of **logic gates**.
Quickly you realize that with every new bit this requires a lot of effort.

In the **second part** (Go on...)
you are working in another **6 experiments**
with pre-programmed comparator semiconductor IC's.
Here you learn that by **cascading**
you can compare basically infinite binary numbers to compare.

Let's go...and have fun...
