High performance Automatic Gain Control. Power is approximated by absolute value.

Here is a diagram showing how it works:

Parameters

(R): Run-time adjustable

Rate (R): The update rate of the loop.
Reference (R): Reference value to adjust signal power to.
Gain (R): Initial gain value.
Max gain (R): Maximum gain value (0 for unlimited)

Example Flowgraph

This flowgraph shows an Automatic Gain Control block in an AM receiver.

+High performance Automatic Gain Control. Power is approximated by absolute value.
-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.

-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.
