I moved your post from the other thread, as it is an other question.
Now you have your own thread.
You don't have to know everything, if you know where to find it.
When you do ask questions, you may look stupid.
When you do NOT ask questions, you will STAY stupid.
It would be nice to have the Timezone ( GMT +/- x ) in the location field in the profile.

That show the simple arrangement of a 2 to 4 bit. By adding a third input stage and four more AND gates you get the 3 to 8 bit. Hint: some of the AND gates will now require 4 inputs max.
Can you show the truth tables for a 2 to 4 and a 3 to 8?
I'm too old.
