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.

This hierarchical block implements the single branch IQ imbalance transmitter and receiver models.

Developed from source (2014): 

   In-Phase and Quadrature Imbalance: Modeling, Estimation, and Compensation

Graph corresponding to the TX origin mode:

Graph corresponding to the RX origin mode:

Parameters

(R): Run-time adjustable

Magnitude (R)
Magnitude in dB
Phase (R)
Dephasing to add in degrees
Origin
Type of impairement

Example Flowgraph

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.
