We modified IMMT2 ADS so that we can implement resG filters in PRCL, SRCL, and MICH controls to suppress the peaks at IMMT2 dither frequencies in their error signals.

We changed the dither frequencies from 30.125 Hz and 32.125 Hz to 9.125 Hz and 19.125 Hz and performed the phasing for these frequencies (fig.1).

According to the phasing results, we set the demod. phases. Also, There seem to be some peaks at -0.875 Hz and +1.125 Hz in bandpassed signals. So we implemented the notch filters for 0.875 Hz and 1.125 Hz in DEMOD_SIG_I.

After that, we engaged IMMT2 ADSs. They seem to work well.
