Exporting a Frame-Based Signal

Using the To Workspace Block

Recall that 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.) When the input to the To Workspace block

is a frame-based signal (and the

Save format parameter is set to Array), the

block creates an P-by-N array in the MATLAB workspace containing the P

most recent samples from each channel. The number of rows, P, is specified by

the

Limit data points to last parameter. The newest samples are added at the

bottom of the matrix.

The figure below illustrates this for three consecutive frames of a frame-based

signal (two samples per frame) exported to matrix
