Interleave

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.

This block can also be viewed as a special case of the Patterned Interleaver in which the pattern is defined by a block size and always goes in sequential order. For example, a Patterned Interleaver block with a pattern  would be the equivalent of this block with BlockSize=2, Num Streams=3.

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:. 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.
