This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]].  This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.


As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.
Deinterleave an input block of samples into N outputs.
 
This block deinterleaves blocks of samples. For each output connection, the input stream will be deinterleaved successively to the output connections.
By default, the block deinterleaves a single input to each output.

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.

Deinterleave an input block of samples into N outputs.

This block deinterleaves blocks of samples. For each output connection, the input stream will be deinterleaved successively to the output connections. By default, the block deinterleaves a single input to each output. 

  blocksize = 1
  connections = 2
  input = [a, b, c, d, e, f, g, h]
  output[0] = [a, c, e, g]
  output[1] = [b, d, f, h]

  blocksize = 2
  connections = 2
  input = [a, b, c, d, e, f, g, h]
  output[0] = [a, b, e, f]
  output[1] = [c, d, g, h]

See also Interleave.

Parameters

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