ALMA MEMO #447

Multi-resolution FX Correlator

John Bunton (CSIRO)

2003/02/27



Keywords : Correlator, FX, Multi-resolution

Future expansions of the ALMA correlator are likely to follow an FX topology. This memo describes the architecture for the filterbanks that naturally lends itself to multi-resolution observing in multiple frequency bands. It is based on a cascade of polyphase filterbanks, this maximizes the signal to noise performance at the highest frequency resolution.
