Accessing Digital Modulation Blocks (Using the Communications Blockset)

Communications Blockset

Accessing Digital Modulation Blocks

You can open the Modulation library by double-clicking on icon in the main Communications Blockset library (commlib), or by typing

```
commmod2
```

at the MATLAB prompt.

Then you can open the Digital Baseband and Digital Passband sublibraries by double-clicking on their icons in the Modulation library, or by typing these commands at the MATLAB prompt.

```
commdigbbnd2
commdigpbnd2
```

The Digital Baseband and Digital Passband libraries have sublibraries of their own. You can open each of these sublibraries by double-clicking on the icon listed in the table below, or by typing its name at the MATLAB prompt.
