    Hi!

    According HVPSFB_User's Guide_v1.1.pdf (p.31):

    "Although not recommended, b2_Gui, b1_Gui, b0_Gui, a2_Gui and a1_Gui values may also be directly changed from the CCS environment using watch views. Please refer to HVPSFB-Calculations.xls file for details on these calculations. The equations for deriving coefficient values based on poles, zeroes, gain and switching frequency are also clear from the GUI source file".

    I have not found more information...

    Regards,
