Graphical user interface that can be used to interactively design wfir filters
[ftype,forder,cfreq,wtype,fpar] = wfir_gui()
| ftype a string: | the selected filter type. |
|---|
: :cfreq a 2 vector: the cut-off frequencies in normalized frequencies : :wtype a string: the selected window type. : :fpar 2-vector of window parameters. :
This function proposes a graphical user interface to allow user interactively select the design parameteres of windowed finite impluse response filters (see `wfir`_). It is called by wfir when no input arguments are given.
If requested, the frequency response of the filter is automatically updated according to the parameters set in the dialog window:
Based on `uicontrol`_ functions.
Version Description 5.4.0 Function wfir_gui is redesigned from scratch to provide a better user experience. .. _uicontrol: uicontrol.html .. _wfir: wfir.html
