DSP Blockset

Example 1: Generating Sample-Based Output

In the model below, the Signal From Workspace block creates a four-channel sample-based signal with the following data:

• Channel 1: 1, 2, 3, 0, 0,...
• Channel 2: -1, -2, -3, 0, 0,...
• Channel 3: 0, 0, 0, 0, 0,...
• Channel 4: 5, 5, 5, 0, 0,...

  

To create the model, specify the following parameter values in the Signal From Workspace block:

• Signal: cat(3,[1 -1;0 5],[2 -2;0 5],[3 -3;0 5])
• Sample time: 1
• Samples per frame: 1
• Form output after final data value: Setting to zero

The Sample time setting of 1 yields a sample-based output with sample period of 1 second. Each of the four elements in the matrix signal represents an independent channel (the channel numbering is arbitrary). The Form output after final data value parameter setting specifies that all outputs after the third are zero.
