I would be interested in your comments. <dan> Dan, I don't have the latest Rochester Conference proceedings. Could you tell me which one you are talking about? I did see the brief description in the RTX Express newsletter. "Sliding" FFTs have been discussed many times. I have not had a chance to actually try one yet. I am not sure if Ting's CFT is equivalent to a "Sliding" FFT. The non-linear nature of the phase relationship generated by the CFT must be considered for the application. The CFT appears to be most appropriate in parallel computing environments. Note that Ting says the CFT is well suited to the RTX2000 with the 16x16 hardware multiplier. The Harris promotion on the RTXEB Contest Board contains an RTX2001A, w/o the multiplier, the reason I decided not to enter the contest.
