Hi Jonathan
This is interesting. Is an inverse PFB is just a PFB using an inverse
FFT? That should be very close by possibly not bit-perfect inversion.
Or are you considering a step-by-step inverse of the PFB algorithm? I'm
interested because there are traps. Small numerical errors are magnified
when you compute the inverse FIR filter on the data after inverse FFT.
At least I think so.
I'd be interested in your implementation of the inverse PFB. You should
publish it.
Thanks
Gerry
The reason I'm asking is that if you lose any

Hello CASPERites,
Has anyone implemented an _inverse_ PFB? That is a block taking channelized
PFB data and reproducing the original time series.
If so, is the code/mdl/yellow block available?
Thanks,
Jonathan
