Deconstructing Multichannel Frame-Based Signals
A frame-based signal with N channels and frame size M is represented by a
sequence of M-by-N matrices. (The special case of N = 1 represents a
single-channel signal.) There are two basic ways to deconstruct a multichannel
frame-based signal:
•Split the channels into independent signals – The constituent channels of a
multichannel frame-based signal can be extracted to form individual frame
based signals (with the same frame rate and size) by using the Multiport
Selector block in the Indexing library (in Signal Management).
•Unbuffer the samples – Multichannel frame-based signals can be unbuffered
into multichannel sample-based signals using the Unbuffer block in the
Buffers library (in Signal Management).
