Virtual Source and Sink

Virtual Source / Sink

If the system is very complex, we can use Hierarchical Blocks to decompose the system into more manageable parts; or employ Virtual Sources and Virtual Sinks to mark and organize the data flow. For information on using Hierarchical Blocks, you can refer to this page. In this section, we will introduce Virtual Sources and Virtual Sinks.

Let's examine the example illustrated in the following figure:

Note

We have added some comments for the Virtual Source and Virtual Sink to make their purpose more clear. You can add comments to many GUI components in this way.

Exercise 4

Create an amplitude modulation (AM) system that has two tabs: "AM Mod" (for modulation) and "AM Dem" (for demodulation) with the following simulation results.
