design filters starting with frequency and magnitude specifications
(filterbuilder
)
description
the filter builder app provides a graphical user interface to design filters using the 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, 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™. for more information on the design process using the filter builder app, see . for details on each of the response methods and settings of all the associated parameters, see .
open the filter builder app
matlab® toolstrip: on the apps tab, under signal processing and communications, click the app icon.
matlab command prompt: enter
filterbuilder
.matlab command prompt: enter
filterbuilder(obj)
, whereobj
is an existing filter object. for example, ifobj
is a bandpass filter,filterbuilder(obj)
opens the bandpass filter design dialog. theobj
object must have been created usingfilterbuilder
or usingfdesign
.matlab command prompt: enter
filterbuilder('response')
to replace response with a supported response method. matlab opens a filter design dialog that corresponds to the specified response. for details on the supported response methods, see .
