We were looking at the response of the ADS loops to the impulse they get when turned on after coil driver switching.  We noticed that ADS DOF3 seems to have a much higher gain, and perhaps some gain peaking, based on a time series of the control and error signals.  Looking at the names of the filters one would think that DOF3 has 20dB less gain than the other DOFs. However, the filters called :0.1, the DOF 3 version has a factor of 50 more gain at DC.  This means that the total filter gain for DOF3 is a factor of 5 higher than the other ADS filters.

It would be nice to move this gain somewhere explicit.  Perhaps we could also consider lowering this gain to stop the gain peaking.
