If you go to www.analog.com/dds then scroll down & select the
"Technical Library" link (under the "Technical Support Resources"
heading) you can download the DDSTutor (900K+ pdf-file).
Then do a Ctrl-F and search for "sweet" in the pdf itself.
Some hints are given there.

Unfortunately, the file does not seem to be available currently. I found
the link for it
(http://www.analog.com/UploadedFiles/...17DDStutor.pdf), but
it takes you to a "not found" page.
