3 Working with Signals
3-58
The following sections explain the two methods of deconstructing multichannel
frame-based signals:
•“Splitting a Multichannel Signal into Individual Signals” on page 3-58
•“Unbuffering a Frame-Based Signal into a Sample-Based Signal” on
page 3-60
The final section explains how to reorder the channels in a frame-based signal
without splitting the channels apart:
•“Reordering Channels in a Frame-Based Multichannel Signal” on page 3-61
Splitting a Multichannel Signal into Individual Signals
You can split a frame-based multichannel signal into its constituent
frame-based signals by using the Multiport Selector block in the Indexing
library (in Signal Management).
Example: Splitting a Multichannel Frame-Based Signal. In the model below, a
three-channel frame-based signal is split into a single-channel frame-based
signal and a two-channel frame-based signal.
