With all the discussion lately regarding DDS and CORDIC, I'm reminded of a question that came up some time ago for which I've never found an answer. Perhaps you enlightened people can enlighten me.
Given a complete DDS chip with a single output channel (e.g. AD9834, AD9835), why would one device favor a cosine LUT versus a sine LUT? On the surface, starting the roller coaster ride at the top of the hill (assuming the phase accumulator starts from zero) seems odd. .73, Brent, KD0GLS, Minneapolis _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
