What is WinFIR?

WinFIR

WinFIR makes it super easy to design Finite Impulse Response filters, or FIR filters for short. This software is built with simplicity in mind, but it doesn't skimp on features! It comes packed with a code editor and frequency analysis tools to help you create the perfect filter.

Why Choose WinFIR?

If you know a bit about FIR filters and what they can do, using WinFIR will feel like a breeze. The interface is all in one place—no need to get lost in endless menus. Everything you need is right there! You can adjust filter coefficients and parameters at the bottom of the screen to tweak the frequency and impulse responses. Plus, you can easily load configurations to analyze frequency responses and optimize your filter design.

Easy Data Management

All your data gets saved as TXT files, which are super easy to handle. This makes keeping track of everything simple!

Create Different Filter Types

With WinFIR, you can generate all sorts of filters: low pass, high pass, band pass, and band stop filters! You have full control over edge and sampling frequencies along with other settings like minimum attenuation and maximum ripple. Talk about flexibility!

Custom Coefficients

You can also configure how many coefficients you want to work with—up to 4095! WinFIR uses the well-known "Parks-McClellan" algorithm for calculating these efficiently.

Edit Easily

The impulse response from your filter coefficients is easy to access through an integrated text editor. You can make quick changes and see how they impact the frequency response right away!

Performance Analysis

You can check out how well your filter performs by changing the format of its coefficients too! WinFIR supports both 32-bit and 64-bit floats as well as integers.

A Reliable Tool for Filter Design

WinFIR is designed specifically for filter creation, analysis, and calculation. It's a dependable tool that helps you synthesize filters effectively. With its visual support, analyzing frequency and impulse responses becomes easier than ever! Plus, thanks to its integrated editor, configuring filter coefficients has never been simpler.
