designCustomFilter

Design custom filter for Analog Devices AD936x RF chip

Add-On Required: This feature requires the Communications Toolbox Support Package for Analog Devices ADALM-Pluto 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. The wizard enables you to design a custom filter for the Analog Devices^® AD936x 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.

If the gain or bandwidth characteristics of the default filter does not satisfy the requirements for your application, use the ADI filter wizard to design a custom filter that meets your specific requirements.

Examples

Change Filter Design in Transmitter

1. Create a transmitter System object, and then open the ADI Filter Wizard.

2. tx = sdrtx('Pluto');
   designCustomFilter(tx)

   

3. Design a new filter. To transfer the new filter settings to the object, click Apply filter design.

Input Arguments

x — Receiver or transmitter

System object

Receiver or transmitter, specified as a System object.

• To create a comm.SDRRxPluto System object, use the sdrrx function.

• To create a comm.SDRTxPluto System object, use the sdrtx function.
