DSP FIR-filter calculator

With this tool you can calculate the filter taps (coefficients) for four types of FIR Kaiser-Bessel filters

  • Low pass
  • High pass
  • Band pass
  • Band stop

depending of the sampling rate, number of taps and attenuation levels.

The list on the right hand side of the window holds the filter coefficients which can be exported to a text file by clicking on the save file menu via the menu bar. The result becomes available in a Public Folders directory.

The tool works very intuitive, as any change in setting parameters the resulting filter curve and list of coefficients is updated immediately.
