Add-On Required: This feature requires the Communications Toolbox Support Package for USRP Embedded Series Radio add-on.

Syntax

designCustomFilter(x)

Description

designCustomFilter(x) 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 x 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 false or true, respectively.

The ADI filter wizard requires these MathWorks® products:

  • MATLAB®

  • Signal Processing Toolbox™

  • DSP System Toolbox™

For instructions on operating the ADI filter wizard, visit the Analog Devices website at MATLAB Filter Design Wizard for AD9361.
