May I suggest doing some simple web searches? For relatively non-technical comparisons of AC-3 and DTS, try searching for "ac-3 dts comparison".

For technical details about each of the formats, here is what I did:

1. I searched for "AC-3" in Google.
2. I clicked on one of the top results: the Wikipedia article on Dolby Digital.
3. I skimmed the article and noticed at the bottom there was a link to the standard. I clicked on it. I arrived at a site that had a PDF of the standard.

As for DTS, that standard is not available for free. However, with a search for "open-source DTS decoder", you can find open-source DTS (and AC-3!) decoder software which you could study and learn from. e.g. libdts, libdca, and AC3Filter.
