Are there any plans to include reconstruction of nonuniform sampling in DRS4 to get uniformly sampled data?
Im now reading article IEEE Trans on Circ. ans Systems I, Vol.55 No.8 sept. 2008 Reconstruction of Nonuniformly Sampled Bandlimited Signals Usinga Differentiator–Multiplier Cascade by Stefan Tertinek and Christian Vogel
and plan to implement it, but may be somebody has it done before me.

Interesting paper. I was not aware of this method. Sounds interesting. AFAIK, nobody has implemented it so far.
My (old) plan was to linearly interpolate samples (something you could do in an FPGA as well), but this will introduce (small) errors. The next best thing would be to do some spline interpolation, but this is time consuming and not suited for an FPGA.
If you get good results with the method above, please let others know about it.
