Appropriate ADC for educational project?

Dear amilcar,

I'd firstly like to introduce myself: My name's David and I'm actually Austrian, having grown up in Greece.

It obviously seems like I got to make some experience with the filtering part, as I've not dealt enough with it.

I'd appreciate if you could send me the code for the sinc^3 filter, so I can start from somewhere.

Also, I didn't exactly understand the role of decimation of the delta-sigma?!

Anyway I'll check out that stuff!

We can also speak German if you want, but I'd prefer English because of terminology! :-)

Thank you very much for your interest!

Sincerely,

David
