Explanation:
For a doublet of doublet you would see 4 peaks. When drawing the splitting tree this becomes obvious. So a splitting tree of a doublet of doublet would look like the following:

Here the proton what we look at in the molecule is the upper line. This proton has two neighbors with different coupling constants
So we start with the proton who has the highest
Now we take the proton with the lower
This gives a signal with a doublet of doublets. Since we use
