[Lofarpwg] PPF for LOFAR

[Jean-Mathias Griessmeier]

Hi,

I have no information about inverting, but I know that Cedric Viou 
<Cedric.Viou at obs-nancay.fr> at Nancay has re-implemented the LOFAR 
polyphase filter for a NenuFAR backend. If you have specific questions 
on this implementation, I can put you in contact with him.

Best wishes,

Jean-Mathias
