Filter Builder
(To be removed) Design filters starting with frequency and magnitude
specifications (filterBuilder)
The Filter Builder app will be removed in a future release. Use the Filter
Designer app or the designfilt function with no input arguments
instead.
Description
The Filter Builder app provides a graphical user interface to
design filters using the fdesign object. The first step is to
choose the filter response. Based on the response you choose, the algorithm,
constraints, and the design parameter settings appear on the Main
tab of the user interface. You can further specify the precision and data types in the
Data Types tab. The Code
Generation tab contains options for various implementations of the
completed filter design. Once you specify all the filter parameters and the design
algorithm, you can visualize the filter response by clicking on the View
Filter Response button. When you click on this button, FVTool opens to display the magnitude response of the filter. When you have
achieved the desired filter response through iterations of design and analysis, click
OK. When you click OK, the app exports the
filter object to the base workspace. If you select the Use a System object to
implement filter check box in the user interface, the app exports a
filter System object™.
