Signal Processing Toolbox 5.1 Release Notes (Signal Processing Toolbox Release Notes)

Signal Processing Toolbox Release Notes

Enhancements

This section describes the Signal Processing Toolbox enhancements and is organized into the following subsections:

FDATool Enhancements

The following items have been added to the FDATool.

The new Filter Visualization (fvtool) can be launched from Analysis->Full View Analysis.
Print Preview is now an icon on the toolbar and it launches the MATLAB standard print preview.
Clicking on any point on a filter plot line adds a data marker, which displays information about the current point.
New windows are included in Method->FIR->Window and in the Window option in the Window Specifications pane.
The ability to export filter coefficients to a C-header file (File->Create Header File) is included.
The raised cosine (firrcos) filter method is a new option in the Method menu and in the Design Filter pane.
A plug-in for Code Compose Studio^TM IDE to provide the ability to download coefficients from FDATool to the Developer's Kit for TI DSP is included.
FDATool is integrated with DSP Blockset and is accessible from the Digital Filter Design block.

SPTool Enhancement

You can print preview and print your filter design in the SPTool Filter Viewer and Filter Designer.

Enhanced Functions

The following functions have been enhanced in the Signal Processing Toolbox 5.1.

Function
Enhancement

buffer
Takes all MATLAB data types in addition to double-precision data

chirp
Allows you to specify the shape (concave or convex) of a quadratic chirp operation

eqtflength
Returns the numerator and denominator orders in addition to the numerator and denominator

lpc
Outputs a vector of prediction error variances in addition to the linear prediction filter coefficients

medfilt1
Allows you to specify the matrix dimension along which the filter operates

sgolayfilt
Allows you to specify the matrix dimension along which the filter operates, and it returns row output for row input. This is consistent with filter
