Open the Filter Design and Analysis Tool.
Syntax
Description
fdatool
opens the Filter Design and Analysis Tool (FDATool). Use this tool to:
Refer to Using FDATool with the Filter Design Toolbox for more information about using the quantization features of FDATool. For general information about using FDATool, refer to Filter Design and Analysis Tool in your Signal Processing Toolbox documentation.
When you open FDATool and you have Filter Design Toolbox installed, FDATool incorporates additional features that are provided by Filter Design Toolbox. With Filter Design Toolbox installed, FDATool lets you design and analyze quantized filters, as well as convert quantized filters to various filter structures, transform filters, and realize models of filters.
Use the Set Quantization Parameters option to configure the quantization settings for a quantized filter, or to access the tools to scale the filter coefficients.
Set Quantization Parameters -- provides access to the properties of the quantizers that compose a quantized filter. When you click Set Quantization Parameters, you see FDATool displaying the quantization parameters at the bottom of the dialog, as shown in the figure.
Transform Filter--clicking this button opens the Frequency Transformations pane so you can use digital frequency transformations to change the magnitude response of your filter.
Realize Model--starting from your quantized, direct form, FIR filter, clicking this button creates a Simulink model of your filter structure in new model window.
Turn quantization on--enables the Quantized Filter panel and quantizes the current filter. Select this option when you want to quantize a filter or set the quantization properties for a filter.
Optimize...--opens the Quantized Optimizations dialog to let you specify how to quantize and scale your filter.
Remarks
By incorporating many advanced filter design methods from Filter Design Toolbox,FDATool provides more design methods than the SPTool Filter Designer.
