Alexandre,

Yes please, get on board!

In the case of the square wave chapter, I had assumed that doing it with 
digital logic would result in either 0 (no amplitude) or 1 (full 
amplitude). So there shouldn't be any DC offset when it's at 0. Of 
course, there are some other real-world problems with those patches, 
namely that there is also no antialiasing.

Since the FLOSS Manuals are "modular", they can be remixed as needed for 
any kind of workshop, class or curriculum, including or leaving out 
sections from all the different FLOSS Manuals as needed.

So my suggestion to you would be to write a short chapter on DC offset 
which can then be referred to in the square wave tutorial, or in any 
other tutorial or manual where such a situation might arise.

Likewise, I'd love it if someone could do a single chapter on the 
different antialiasing methods (Miller's, Frank's...). The idea would be 
to simplify the explanations so that one doesn't need a background in 
DSP or computer science in order to understand them.

Would you be interested to do either of those?
