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.
<p>This block has been deprecated. Use block [[Fractional Resampler]] instead.</p>

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.

Interpolating MMSE filter

This block has been deprecated. Use block Fractional Resampler instead.

Parameters

(R): Run-time adjustable

Phase Shift
The phase shift of the output signal to the input
Resampling Ratio (R)
The interpolation ratio = input_rate / output_rate.
