| May 2, 2018 at 16:40 | comment | added | a concerned citizen | I had written this as a comment so that the answer to which I am making the comment can be updated, if necessary. But if you say it should be an answer, so be it. I don't know where did the "stupid" come from. | |
| May 2, 2018 at 16:29 | comment | added | Andy aka | @aconcernedcitizen why not make this an answer rather than pinning it to my answer unless, of course you are too-subtley pointing out an error in my answer that I'm too stupid to recognize? | |
| May 2, 2018 at 16:25 | comment | added | a concerned citizen | The reason the polynomial is different is for the frequency scaling. A non-scaled Bessel (OP's first formula) will have \$\omega_0=\sqrt{3}\$, with an attenuation of ~-1.597dB@1Hz -- nothing unusual, Bessel is normally for flat group delay, not frequency -- so TI scaled it so that it's the classical -3dB. | |
