Owning Palette: Adaptive Filters VIs

Requires: Adaptive Filter Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Fixed-Point VIs to simulate the behaviors of the fixed-point adaptive filter, save the fixed-point settings to an XML file, and load the fixed-point settings from an XML file.

The VIs on this palette can return general LabVIEW error codes or specific Adaptive Filter error codes.

Palette ObjectDescription
AFT Load Fixed-Point SettingsLoads the settings of a fixed-point adaptive filter that you saved to an XML file.
AFT Save Fixed-Point SettingsSaves the settings of a fixed-point adaptive filter to an XML file. You can determine appropriate settings for a fixed-point adaptive filter by simulating the filter. Use the AFT Load Fixed-Point Settings VI to load the fixed-point settings from an XML file.
AFT Simulate Fixed-Point FIR LMSConfigures the settings of a fixed-point adaptive filter and simulates the performance of this filter. You also can save the fixed-point adaptive filter settings to an XML file. After you place this Express VI on the block diagram, double-click this Express VI to display the configuration dialog box.

After you determine the fixed-point settings, you can use these settings to generate LabVIEW FPGA code for the fixed-point adaptive filter.
