Deconstructing Signals

3-59

To build the model, make the following parameter settings:

•In Signal From Workspace, set:

Signal = [1:10;-1:-1:-10;5*ones(1,10)]'

Samples per frame = 4

•In Multiport Selector, set:

Select = Columns

- Indices to output = {[1 3],2}

The top (4-by-2) output from the Multiport Selector block contains the first and

third input channels, and the bottom output contains the second input channel.

The Multiport Selector block preserves the frame rate and frame size of the

input as long as

Select is set to Columns. See “Frame-Based Multichannel

Signals” on page 3-12 for more about frame-based signals.

Note that you could also create or import the two signals by using two distinct

Signal From Workspace blocks. See the following sections for more

information:

•“Creating Signals Using the Signal From Workspace Block” on page 3-38

•“Importing a Multichannel Frame-Based Signal” on page 3-68
