Deconstructing Signals

Multichannel signals, represented by matrices in Simulink, are frequently used in DSP models for efficiency and compactness. An M-by-N sample-based multichannel signal represents M*N independent signals (one sample from each), whereas an M-by-N frame-based multichannel signal represents N independent channels (M consecutive samples from each). See Multichannel Signals for more information about the matrix format.

Even though most of the DSP blocks can process multichannel signals, you may sometimes need to access just one channel or a particular range of samples in a multichannel signal. There are a variety of ways to deconstruct multichannel signals, the most common of which are explained in the following sections:

• Deconstructing Multichannel Sample-Based Signals
• Deconstructing Multichannel Frame-Based Signals

For information about constructing multichannel signals from individual sample-based or frame-based signals, see these sections:
