 Line 22:
- *[[CLIO/data/FrequencyNoise|周波数雑音]]: inline armのerror信号を1e12[V/m], cavity pole 248Hzで換算してプロット。換算係数は100kHz付近のスペクトル形状が変位雑音と一致するように選んだ。8kHz以上で感度を制限。
+ *[[CLIO/data/FrequencyNoise|周波数雑音]]
 Line 28:
- *[[FeedbackFilter|フィルタ雑音]]: [[http://gw.icrr.u-tokyo.ac.jp:8888/clio_blog/2008/10/mass-filter-circuit-noise.html|前出]]のフィルタの入力換算雑音vnを補正。error basedの感度、feedback basedの感度でフィルタ雑音の現れ方が変わる。ライン以外では今は問題なし。
  *feedback basedの場合: dx_filerr = vn / H (Hは干渉計の応答)
  *error basedの場合: dx_filfb = vn G / H (Gはopenloop伝達関数)
+ *[[FeedbackFilter|サーボフィルタ雑音]]
