New Numerically Controlled Oscillator (NCO) Block

The NCO block in the Signal Operations library is new for this release.

Digital Filter Block Enhancements

Significant enhancements were made to the Digital Filter block for this release:

• Digital Filter can now operate in two different modes, which you select in the Filter source group box. If you select Specify filter characteristics in dialog, you enter information about the filter in the block mask as in previous releases. If you select Specify discrete-time filter object (DFILT), you can now specify the filter using a dfilt object from the Signal Processing Toolbox product.

• You can now open the Signal Processing Toolbox fvtool from the Digital Filter block mask to view the filter response.

Fixed-Point Support Added to the Matrix Multiply Block

The Matrix Multiply block now has functionality identical to the Simulink Product block. The block now supports Boolean, integer, and fixed-point data types.

Simulink Virtual Bus Support Added to Key Blocks

Simulink^® virtual bus support has been added to the following blocks:

• DCT

• Delay

• Flip

• Overwrite Values

• Submatrix

• Transpose

For more information on virtual buses, refer to "Using Buses" in the Using Simulink documentation.

New Audio Sample Rate Conversion Demo

The new Audio Sample Rate Conversion demo illustrates audio sample rate conversion of a 48 kHz (DAT sampling rate) input audio signal to a 44.1 kHz (CD sampling rate) output audio signal using a multistage multirate FIR rate conversion approach. You can access this demo from the Demos pane of the Help browser under Blocksets > Signal Processing > Audio Processing.
