I've seen the term used as "DDS signal" and "DDS function".

I've searched the web but found no conclusive definition.

What is DDS?

Thanks,

Dave,

Simply put it is a way to generate signals digitally using lookup table.

Imagine digitizing a sine wave, measuring voltage of the signal at various equally divided points of the curve. For DDS: Now take those data and reverse it by generating those voltages at various points in time and you have a very good simulation of a sine curve (or any signal). That's DDS.

DDS can be used to generate a very good likeness of many types of signal. Because it is digital there can be some digital artifacts that might need smoothing out.
