  This program is a stand-alone version of the polyphase
  filter bank generator I designed and implemented for the
  LOFAR telescope (http://www.lofar.org/). This code
  generates the filter weights for polyphase filter banks
  with arbitrary numbers of channels, and with configurable
  windows. The original code is a part of the LOFAR
  real-time central processor (the correlator). The code is
  completely generic, and can be used for other telescopes,
  or even completely different signal processing
  applications as well. The LOFAR subband data are processed
  by a Poly-Phase Filter bank (PPF) that splits a frequency
  subband into a number of narrower frequency channels. In
  this step, we trade time resolution for frequency
  resolution: we split a subband into N separate channels,
  but with an N-times lower sampling rate per channel.
