DESCRIPTION:The M-path polyphase analysis filter bank channelizer is quite 
 a remarkable digital signal processing algorithm. In its simplest realizat
 ion\, the maximally decimated filter bank\, the bank outputs M baseband ti
 me series from translated spectral spans with bandwidth and sample rate fs
 /M from M spectral bands centered at integer multiples of fs/M. Modificati
 ons to the channelizer are many and include offsets of channelizer center 
 frequencies\, non-maximal decimation from M-to-1 to M/2-to-1 or to 3M/4-to
 -1 along with various post channelization signal conditioning options. We 
 present a set of severe channelizer specifications and illustrate various 
 channelizer modifications to reduce processing cost while meeting original
  design specifications. Some of the new variations offer quite substantial
  reductions in workload by very simple changes in perspective and design o
 ptions.\n\nSpeaker(s): prof fred harris\, \n\nAgenda: \n6:30-7:00 (PST) PM
