Design custom filter for Analog Devices AD9361 RF chip


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. 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 a comm.SDRRxE3xx or comm.SDRTxE3xx 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 the following MathWorks® products:


  • 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.
