Working with Sources and Sinks
Two essential features of every Simulink model are data sources and data sinks. These provide the means for initiating signal flow in a system, and for analyzing the system's response during and after the simulation. The Blockset's DSP Sources library contains blocks for importing data from the workspace, file, and sound device, and for generating constant and time-varying signals. The DSP Sinks library provides blocks for exporting data to the workspace, file, and sound device, and for visualizing time-domain and frequency-domain signals on the screen.
