Design custom filter for Analog Devices AD936x 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. 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.
Change Filter Design in Transmitter
Create a transmitter System object, and then open the ADI Filter Wizard.
tx = sdrtx('Pluto'); designCustomFilter(tx)
Design a new filter. To transfer the new filter settings to the object, click Apply filter design.
