Editing Building Circuits with Words (section)

=== Step 1: Describe the green outputs ===
Let's take a look at the XOR level and its truth table

'''We want to describe each combination, that turns the desired output''' {{On}}

What's the idea? If we make sure that our circuit outputs {{On}} in all relevant cases, then it automatically outputs {{Off}} in all other cases. So we only have to focus on the {{On}} and get the {{Off}}s for free.

Start like this:

There are 2 columns, that turn the desired output to {{On}}.

Let's start with the first and expand our descriptive sentence.

Nice! Okay that's the first column - now let's add the second.

We now have a complete description when our circuit outputs {{On}}
