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.

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.
