Communications Blockset Release Notes

Obsolete Blocks from Previous Manual

The table below lists blocks that appear in the previous version of the Communications Toolbox User's Guide but that are not included in the Release 12 Communications Blockset. Where applicable, the second column lists blocks that provide similar functionality. In some cases, the similar block requires different parameter settings, data formats, or signal attributes compared to the original block. Therefore, you should read the documentation for the similar block before using it in your model.
