Design custom filter for Analog Devices AD9361 RF chip
designCustomFilter( opens the ADI
filter wizard application. Use the ADI filter wizard to change the default
filter design applied to the filter chain in the receiver or transmitter
System object™ specified by
x. For example, if the gain or
bandwidth characteristics of the default filter does not satisfy the
requirements for your application, you can design a custom filter that meets
your specific requirements. The wizard enables you to design a custom filter for
the Analog Devices® AD9361 RF chip based on the
BasebandSampleRate property of the object. You can
adjust and optimize the settings for calculating the analog filters, the
interpolation and decimation filters, and the FIR coefficients.
When applying a custom filter to the
System object, the
UseCustomFilter property of the object
is set to
true. To switch between the default and your custom
filter design, set the
UseCustomFilter property to
The ADI filter wizard requires these MathWorks® products:
Signal Processing Toolbox™
DSP System Toolbox™
