I dont understand about magnitude e quals 1.646756*sqrt(I^2+Q^2) ,Why about 1.646756. I dont understand about phase e quals 64*atan2(Q, I) in the range [-201,201en-USTelligent Community 13Thu, 05 Mar 2020 12:45:06 GMThttps://devzone.nordicsemi.com/thread/238288?ContentTypeID=1Thu, 05 Mar 2020 12:45:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5a68b4e1-bdd7-48ed-81d4-b403f0846badketiljo<p>The Direction finding feature employs fixed-point arithmetic.</p> <p>The factor of 1.646756 is an artefact of the fixed-point calculation. Only relative amplitudes between antennas are necessary for direction finding, so this factor can be ignored.</p> <p>The range of atan2 is [-pi,pi]. Multiplied by 64 this is [-201.06,201.06]. The output is only whole integers, limiting the range to -201 to 201 with a resolution of 0.895 degrees.</p><div style="clear:both;"></div>
