Description:
FIR Design Tool is a tool to interactively design and evaluate FIR digital filters with high-performance and high-stability. You can generate tap coefficients for FIR filters from the frequency characteristics you desire and evaluate the frequency characteristics calculated from the tap coefficients 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
- Defining an arbitrary frequency characteristics to design filters
- Displaying tap coefficients and the window function
- Floating point data load/save brings accurate evaluation of highly attenuated signals.

Key Specifications
