3 Working with Signals
3-46
frame-based signals using the Buffer block in the Buffers library (in Signal
Management).
The following sections explain the two methods of constructing multichannel
frame-based signals:
•“Concatenating Independent Frame-Based Signals into Multichannel
Signals” on page 3-46
•“Buffering Sample-Based and Frame-Based Signals” on page 3-47
Concatenating Independent Frame-Based Signals
into Multichannel Signals
You can combine existing frame-based signals into a larger multichannel
signal by using the Matrix Concatenation block in Simulink’s Sources library.
All signals must have the same frame rate and frame size.
Example: Concatenating Frame-Based Signals. In the model below, a single-channel
frame-based signal is combined with a two-channel frame-based signal to
produce a three-channel frame-based signal.
