I enabled dewhitening filters of BFV by setting config board on BFV coil driver.
Fig1 shows the config board setting (2-stage dewhitening filters are on for all coil driver output).
To compensate the dewhitening filter, I set filters at FM9 and FM10 of COILOUTF_V{1,2,3} as shown in fig2.

This setup is temporal one, so it will be changed during DGS mentainance tomorrow.
