I performed the noise budget of the DAC noise for BS, SR2 and SR3 by turned off the de-whitening filters in coil driver.
BS, SR2, SR3 TM 1 stage -> 0 stage
BS, SR2, SR3 IMV/IMH 2 stage -> 0 stage

No significant change was detected in DARM sensitivity when we turned off the de-whitening filter.
So, the DAC noise from Type-B suspension was lower than 1/10 in current DARM sensitivity.

All results were placed in

(Blue : current sensitivity Red : DAC de-whitening filter off for certain stage.)
