Welcome to the Igor Filter Design Laboratory (IFDL) Demo!

  This demo version of IFDL allows you to design your own Kaiser
  Low Pass filters and other Window Filters, and apply them to your data.

  You can compare the responses of two filters, save the filter
  coefficients for use in other programs, and print a report
  showing a filter's response and coefficient values.

  Pre-computed examples of McClellan-Parks-Rabiner (MPR) filters
  and Kaiser Maximal Flatness filters are provided.

  This demo version ignores changes to the design parameters for
  these filter types.

  Purchase IFDL to enable the Kaiser Maximally Flat and all
  the MPR filters, and to receive a full electronic and printed manual.

  You can purchase IFDL from WaveMetrics, Inc. by calling (503)-620-3001,
