FIRit is a unique FIR filter design software. It enables you to design a FIR filter very quickly and to experiment with different filter properties and target responses.

Use FIRit to design a FIR filter in 4 easy and quick steps: 
1) Load a measurement from a simple ASCII text file
2) Select a predefined frequency domain target response or define one yourself
3) Fine-tune your design like linear phase vs. minimum phase design
4) Select sampling rate and filter length for your target system and export to it.

Features:
- Easy and quick FIR filter creation
- Optionally based on an imported measurement
- Design linear-phase or minimum-phase FIR filters
- Target presets for magnitude: Flat or user defined (linear or minimum phase filter)
- Target presets for phase: Flat phase, minimum phase or user defined
- Combine magnitude and phase presets
- Define filter response by value table or based on IIR designs
- Export filter coefficients as ASCII text file
- Support for different sample rates and filter lengths
