Variable Clock Architecture for ARBs Avoids the Limitations of DDS (175.09 KB)

Recently, function generators based on direct digital synthesis (DDS) have been developed into arbitrary/function generators with impressive specifications. However, the DDS approach to arbitrary waveform generation imposes serious limitations which are not immediately obvious. The alternative approach of a variable clock architecture offers a greater level of flexibility and can be used to solve many more real-world problems.
