Description
|
|
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
This format contains sequence of complex number samples. Each complex
|
|
|
|
|
number consist two parts, called In-phase and Quadrature (IQ). Both I
|
|
|
|
|
and Q are represented as a 8 bit unsigned number. I value comes first
|
|
|
|
|
and Q value after that.

[media] v4l: doc: Remove row numbers from tables
Shorten the tables by removing row numbers in comments, allowing for
later insertion of rows with minimal diffs.
