Digital Filter Coefficients Generator (GTK+)
Copyright © 1994-2022 Ralf Hoppe
Overview
DFCGen, the Digital Filter Coefficients Generator is a free software tool for the design of time-discrete (digital) filters/systems.
It supports you in analysis and synthesis of linear time-invariant time-discrete (LTI) systems from the theoretical point of view.
In particular it generates the system transfer function coefficients in Z-domain based on the type and the specific parameters of a chosen system.
DFCGen supports:
- Linear FIR systems of various characteristics with windowing functions as Hamming, Hanning, Blackman or Kaiser window
- Standard IIR filters like Cauer, Chebyshev, Butterworth and Bessel
- Various systems of free degree as e.g. Integrator, Hilbert transformer, Comb filter etc.
- Predefined systems with determined coefficients (and degree), e.g. fitting filters, differentiators, etc.
- Frequency transformation into high-pass, band-pass and band-stop
- Edit of coefficients (change, delete, round)
- Pole/Zero analysis
- Graphical visualisation of system characteristics (plots) like magnitude response, phase response, attenuation, characteristic function, group delay, phase delay, impulse response and step response
- In plots: zoom, lin./log. and auto-scaling
- Printing of coefficients and response plots
- Save and load of the defined filter
- Export of coefficients to plain text, "C" language and MATLAB scripts
