embedd the resampler between the input integrator and the output comb.... filter becomes a hogenauer filter instead of CIC.. I always recommend to avoid using the cic.... the polyphase will outperfomr the cic in number of registers and width of adders ..

Thank fred and welcome to the conference.
Yes, agreed, I referenced hogenauer in the presentation.
I also referenced your excellent presentation from last year, regarding PP filters.
I'm looking forward to your talks later :-)

11:52:19	 From  AllenK : Thanks very much for the talk, John!  I am used to the idea of "asynchronous messaging", where you don't know when a message will come in.  For "asynchronous clocks" am I correct in assuming that the sample rate is known ahead of time, but that they are not synchronized in a ratio of integers?
12:18:18	 From  AllenK : Oh, I see now, thanks.
