R11.1 Blocks Have Been Removed in R2007a — Run Helper Script Before Upgrading
X-Axis Control Added to Spectrum Scope and Vector Scope Blocks
Fixed-Point Support and Tunability Added to Filter Design Toolbox Library Blocks
The R11.1 DSP Blockset blocks have been deprecated since R14SP2. These blocks have been completely removed from the Signal Processing Blockset product in R2007a.
We are providing a script and documentation to help you remove any R11.1 DSP Blockset blocks from your models and replace them with current Signal Processing Blockset blocks. You must run this script before upgrading to R2007a. Refer to our MATLAB Central submission titled "Tool for Removing R11 DSP Blockset Blocks from Models" on the Web to download the script and its associated documentation.
The Kalman Filter block has been added to the Filtering > Adaptive Filters library. This block predicts or estimates the state of a dynamic system from a series of incomplete or noisy measurements. See the block reference page for more information.
Unsigned integer and fixed-point data type support has been added to the following blocks:
Support for N-D signals has been added to the following blocks:
More x-axis control has been added to the Spectrum Scope and Vector Scope blocks:
You can now specify the range of the x-axis for the Spectrum Scope and Vector Scope blocks.
You can now specify an x-offset for the Vector Scope block.
See the block reference pages for more information.
The following blocks have been added to the Filter Design Toolbox library:
Arbitrary Magnitude Filter
See the block reference pages for more information.
The blocks in the Filter Design Toolbox library now support fixed-point and integer data types on their input and output ports. In addition, parameters of these blocks that do not change filter order or structure are now tunable.
The Inherit FFT length from input dimensions and FFT length parameters have been added to the FFT and IFFT blocks. See the block reference pages for more information.
The Zero Pad block has been removed from the Signal Processing Blockset product.
You can use the Pad block with the Pad value parameter set to 0 to exactly replicate the functionality of the Zero Pad block. Any Zero Pad blocks in existing models will be automatically replaced by Pad blocks with the Pad value parameter set to 0. Your models will continue to work correctly.
You can use the Pad block to truncate a signal by specifying an output length that is shorter than the input length in a given dimension. In previous releases, the block ignored the value of the Pad signal at parameter and always truncated the end of a signal.
The Pad block now obeys the Pad signal at parameter for truncation as well as for padding, enabling you to truncate a signal at its beginning, end, or both. To get the previous behavior, make sure that the Pad signal at parameter is set to End for any Pad blocks in your model that are truncating the input signal.
The Vorbis Decoder demo has been added to the Audio Processing library. This demo implements the Vorbis decoder, which is a freeware, open-source alternative to the MP3 standard. This audio decoding standard supports the segmentation of encoded data into small packets for network transmission. Open this demo by typing dspvorbisdec.
The Internet Low Bit-Rate Codec (iLBC) demo in the Audio Processing library has been improved. This demo now supports single-precision floating-point data, and both builds and runs faster. Open this demo by typing dspilbc.
