specify frequencies as absolute values or normalized to sampling or Nyquist frequency.

tooltips for all UI widgets and help files.

enhanced matplotlib NavigationToolbar (nicer icons, additional functions).specifications are remembered when switching between filter design methods.only widgets needed for the currently selected design method are visible.Filter coefficients and poles / zeroes can be displayed, edited and quantized in various formats.Compare filter designs for a given set of specifications and different design methods.Fine-tune manually the filter order and corner frequencies calculated by minimum order algorithms.Second-Order Sections are used in the filter design when available for more robust filter design and analysis.Design methods: Equiripple, Firwin, Moving Average, Bessel, Butterworth, Elliptic, Chebyshev 1 and 2 (from scipy.signal and custom methods).Layout and some default paths can be customized using the file pyfda/pyfda_rc.py, at the moment you have to edit that file at its original location. You can also define one or more user directories containing your own widgets and / or filters. Widgets and filters can be enabled / disabled via the file nf.Logging verbosity can be controlled via the file pyfda_log.conf.The location of the following two configuration files (copied to user space) can be checked via the tab Files -> About: Installation from PyPI works the usual way, required libraries are installed automatically if missing:

As pyfda is a pure Python project (no binaries, no compilation required), you can install pyfda using one of the following options: pip There is only one version of pyfda for all supported operating systems, Python and Qt versions. Unless running a binary, you need to have a working Python installation on your computer, preferrably including the libraries listed above.

xlwt and / or XlsxWriter for exporting filter coefficients as *.xls(x) files.

docutils for rich text in documentation.

The following libraries are required and automatically installed by pip when missing. All operating systems - there should be no OS specific requirements.Some Linux distros have built-in flatpak support, for others it's easy to install with e.g. For details, see INSTALLATION.md.Ī flatpak (Linux only) for pyfda is available on Flathub.

No additionaly software / libraries need to be installed. The binaries don't modify the system (except for two ASCII configuration files and a log file), they self-extract to a temporary directory that is automatically deleted when pyfda is terminated (except when it crashes).

Binaries / BundlesĬurrently, binaries (created with pyInstaller) are provided for 64 bit Windows and for OS X. Pyfda source code ist distributed under a permissive MIT license, binaries / bundles come with a GPLv3 license due to bundled components with stricter licenses.

Fixpoint filter implementations (for some filter types) can be simulated and tested for overflow and quantization behaviour in the time and frequency domain. Pyfda is a tool written in Python / Qt for analyzing and designing discrete time filters with a user-friendly GUI.
