Each complex number 16 consist two parts, called In-phase and Quadrature (IQ). Both I and Q are 17 represented as a 14 bit signed little endian number. I value comes first 18 and Q value after that. 14 bit value is stored in 16 bit space with unused 19 high bits padded with 0. 20 </para> 21 <example> 22 <title><constant>V4L2_SDR_FMT_CS14LE</constant> 1 sample</title> 23 <formalpara> 24 <title>Byte Order.</title> 25 <para>Each cell is one byte. 26 <informaltable frame="none"> 27 <tgroup cols="3" align="center"> 28 <colspec align="left" colwidth="2*" /> 29 <tbody valign="top"> 30 <row> 31 <entry>start + 0:</entry> 32 <entry>I'<subscript>0[7:0]</subscript></entry> 33 <entry>I'<subscript>0[13:8]</subscript></entry> 34 </row> 35 <row> 36 <entry>start + 2:</entry> 37 <entry>Q'<subscript>0[7:0]</subscript></entry> 38 <entry>Q'<subscript>0[13:8]</subscript></entry> 39 </row> 40 </tbody> 41 </tgroup> 42 </informaltable> 43 </para> 44 </formalpara> 45 </example> 46 </refsect1> 47 </refentry>
