Dear All - On Monday 5th December, I sent an email to the CASPER mailing list, in which I stated "Randy McCullough understands that in the FPGA implementation of a PFB/FFT, each sample is only used once." In fact, this statement was incorrect; this is not Randy's understanding of how the FPGA PFB works. I apologize for any confusion and/or inconvenience that this portion of my post may have caused.
Regards, Richard
