Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
Below is a simple flowgraph example interleaving two vector sources:

The block properties are set for block size 2 so it passes two outputs from a given vector source before switching.
 
[[File:Interleave_example_properties.png|500px]]
 
 
For this example that means the output begins with: <code>0, 1, 10, 11, 2, 3, 12, 13, 0, 1, ...</code>. The output is graphed below using a [[QT_GUI_Time_Sink|QT GUI Time Sink Block]] with a positive slope trigger. This is why the output displayed begins at 1 instead of zero.

Interleave N inputs into a single output

This block interleaves blocks of samples. For each input connection, the samples are interleaved successively to the output connection.

Parameters

Num Streams
Total number of input ports
Block size
Number of items from one input to output before switching to the next input
Vector length
Number of samples in a vector item

Example Flowgraph

Below is a simple flowgraph example interleaving two vector sources:

The block properties are set for block size 2 so it passes two outputs from a given vector source before switching.

For this example that means the output begins with: 0, 1, 10, 11, 2, 3, 12, 13, 0, 1, .... The output is graphed below using a QT GUI Time Sink Block with a positive slope trigger. This is why the output displayed begins at 1 instead of zero.
