DADiSP Software
Modules - DADiSP/Filters
 DADiSP/Filters
is a menu-driven module for FIR and IIR digital filter design and analysis.
From any DADiSP
Worksheet, you can quickly design, view and analyse both FIR (Finite
Impulse Response) and IIR (Infinite Impulse Response) filters. Once you
have designed a filter, you may filter the raw data, then view and analyse
the filtered signal. Through the easy-to-use dialog boxes or simple one
line functions, you can tune the filter iteratively, re-filtering the
data until you have separated the signal from the noise cleanly.

New Features
DADiSP/Filters Version 5.0 includes a completely redesigned user interface
to streamline the process of designing and applying digital filters. Straightforward
dialogue boxes with automatic option validation simplifies both the design
and analysis of filters.
Filter coefficients can be easily converted to various filter structures
and quantization routines are included to help simulate DSP chipsets.
IIR Bessel filters and the Matched Z Transform design method have been
added. Linear phase FIR Kaiser filters have been expanded and enhanced.
Both time and frequency domain filtering routines have been optimised
to provide more efficient filter processing.
Filters 5.0 New Features Summary
- Streamlined Interface
- IIR Bessel Filters
- IIR Matched Z Design Algorithm
- Improved FIR Kaiser Window Filters
- Coefficient Conversion and Quantisation
- Optimised Filter Processing Functions
