while hunting for the software I had used before, I ran across a newer
paper by Toroysan and Wilson titled "Exact analysis of DDS spurs and SNR
due to phase truncation and arbitrary phase-to-amplitude errors" , aug
2005 frequency control symposium.
Toroysan has a patent on a system for designing DDSes too.
Vankka's book/dissertation is online, as well.
