Configure the Simulink Environment for Signal Processing Models
About DSP Simulink Model Templates
The DSP Simulink® model templates let you automatically configure the Simulink environment with the recommended settings for digital signal processing modeling. DSP Simulink model templates enable reuse of settings, including configuration parameters. You can create models from templates that use best practices and take advantage of previous solutions to common problems. Instead of the default canvas of a new model, select a template model to help you get started.
For more information on Simulink model templates, see Create Template from Model (Simulink).
Create Model Using the DSP System Toolbox Simulink Model Template
To create a new blank model and open the library browser:
On the MATLAB® Home tab, click Simulink.
Click on DSP System to create an empty model with settings suitable for use with DSP System Toolbox™. The new model opens. To access the library browser, click Library Browser on the model toolstrip.
The new model using the template settings and contents appears in the Simulink Editor. The model is only in memory until you save it.
DSP Simulink Model Templates
When you create a model by choosing one of the DSP Simulink model templates, the model is configured to use the settings recommended for DSP System Toolbox. Some of these settings are:
The DSP Simulink model templates are:
DSP System Template
Click on DSP System to create a blank model configured with settings recommended for DSP System Toolbox.
Basic Filter Template
Click on Basic Filter to create a basic filtering model configured with settings recommended for DSP System Toolbox.
This model implements a low pass filter and enables you to compare the filtered signal with the original signal. The model acts as a starting point for modeling filtering algorithms in Simulink using DSP System Toolbox.
Mixed-Signal System Template
Click the Mixed-Signal System template to create a basic A/D converter model configured with settings recommended for DSP System Toolbox and mixed-signal systems. This model performs A/D conversion by implementing an analog anti aliasing filter followed by a zero-order hold circuit. The model acts as a starting point for modeling mixed-signal systems in Simulink using DSP System Toolbox. All discrete-time signals are colored in red to indicate the fastest sample rate. Continuous-time signals are colored in black. For additional sample time options, in the Debug tab, select Information Overlays > Colors.
