DSP Blockset    
Convert Complex DSP To Simulink

Convert complex data from the DSP Blockset Version 2.2 format to the Simulink  Version 3 format.

Library

Description

The Convert Complex DSP To Simulink block accepts complex data (scalar, vector, matrix) in the DSP Blockset Version 2.2 format, and outputs the same data in the Simulink Version 3 complex format. Only complex data should be supplied to this block.

Blocks provided in Release 11 and later blocksets (e.g., Simulink Version 3.0, DSP Blockset Version 3.0, Fixed Point Blockset Version 2.0) use the Simulink Version 3 complex format, which is not compatible with the DSP Blockset Version 2.2 complex format. To add a new block or subsystem (Release 11 and later) to an existing model that uses the DSP Blockset Version 2.2 complex data format, precede it with the Convert Complex DSP To Simulink block. If the new block or subsystem's output is complex, you should follow it with the complementary Convert Complex Simulink To DSP block (unless the downstream blocks have already been updated to their Release 11 counterparts).

These convertor blocks are only needed for interfacing Version 3.0 blocks to the complex-data section of a Version 2.2 or earlier model. Version 3.0 blocks can be added to real-data sections of older models without any data format conversion.

The following figure shows how you can use these two convertor blocks to migrate part of a complex-data model to the Version 3.0 complex format while letting other components continue to use the Version 2.2 complex-data format.
