Digital Filter Coefficients Generator (GTK+)
Copyright © 1994-2020 Ralf Hoppe
A free
tool for the design of time-discrete
(digital) filters/systems.
DFCGen, the Digital Filter Coefficients Generator, is a free
tool/program, which may assist you in the design of digital filters. It
supports the engineer in analysis and synthesis of linear
time-invariant time-discrete (LTI) systems from the theoretical point
of view. It performs generation of system transfer function
coefficients in the 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, integrators 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) as
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
