Fig. 7From: PIONEERS: a 6DoF motion sensor to measure rotation and tides in the Solar SystemNumerical calculation of the ASD of a pure sine with white noise for different observation duration of 8 (a), 32 (b) and 256 (c) times the target signal period. The traditional approximation (green line) fails to predict the ASD value, while Eq. (23) (cyan line) successfully provides the effective amplitude of the signalBack to article page
