The number is in range of +-1.000 on 15-bits (14:0).</P> <P>Attached is the excel sheet for this calculation too.</P> <P>I hope it could help you in your task.</P> <P>Best Regards,</P> <P>Stano.</P> Thu, 09 Sep 2021 11:32:46 GMT StanoA 2021-09-09T11:32:46Z https://community.nxp.com/t5/S12-MagniV-Microcontrollers/MM9Z1-638-Filter/m-p/1336929#M18163 <P>Hi,</P><P>some weeks ago I added a question regarding the Filter of the MagniV.</P><P>Now, I´ve got an additional question....</P><P>At page 139 of the manual of the MM9Z1_638&nbsp; I found the main structure of the implemented low pass filter. In table 192, I found the value conversation: "Data Format: MSB = Sign (“1” minus)"</P><P>Does it mean, you are using the twos complement? and is there an excel sheet aviable to calculate new values?</P><P>regards.</P> Wed, 08 Sep 2021 14:22:00 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/MM9Z1-638-Filter/m-p/1336929#M18163 Boris_Bloxsberg 2021-09-08T14:22:00Z https://community.nxp.com/t5/S12-MagniV-Microcontrollers/MM9Z1-638-Filter/m-p/1337702#M18168 <P>Hi Boris,</P> <P>It is used the fractional arithmetic in this case so the MSB is sign bit.
