Description:
IIR Design Tool is a tool to interactively design and evaluate IIR digital filters with high-performance and high-stability. You can generate tap coefficients for IIR filters calculated by z-transform from the analog model and evaluate the frequency characteristics as well as you can apply the filter to signals in WAVE files to output filtered signals on the screen. In addition, the filtered signal can be saved to another WAVE file.

Main Features
- Frequency characteristics display on a large screen
- Magnify button enables you to confirm details of frequency characteristics.
- On-screen-text enables you to always monitor gains according to frequencies you desire.
- Saving/loading tap coefficients and filter design parameter to/form a file
- Filtering signals on WAV files and displaying the result on the screen
- Filtering signals on WAV files and storing the result to another file
- Evaluating tap coefficients calculated in another system via a coefficients file
- Designing equalizers in addition to LPF/HPF/BPF/BEF
- Displaying poles and zeros for both digital and analog model

Key Specifications
- Filter mode: Butterworth/Chebyshev/Equalizer/Sallen&Key
