Igor Filter Design Laboratory, Version 4
Igor Filter Design Laboratory (IFDL) is a sophisticated and flexible environment for interactive design, evaluation, and application of Finite Impulse Response (FIR) and Infinite Impulse Response (IIR) digital filters.
IFDL is meant to be used by people with some knowledge of digital filters and Digital Signal Processing.
Applications of IFDL
- Designing IIR & FIR filters for use with external programs or hardware.
- Designing filters to be used within Igor to filter your data.
- Experimenting with Digital Signal Processing (DSP) techniques.
IFDL consists of Igor procedure files and specialized functions and operations.
IFDL is built into Igor 8.
(Igor 6 and later include a simplified Filter Design feature suitable for designing simple FIR and IIR filters.)
IFDL 4 can be added to Igor 7 or earlier by purchasing IFDL separately. Contact firstname.lastname@example.org to purchase this additional software.
