IR transmission and calibrated error signal
This is the characterization of IR transmission and the corresponding calibrated error signal. It is shown in picture 1.

This calibration factor is measured while sine wave noise frequency is 28kHz. I also did the measurement for different sine wave frequency. It is shown in picture 2. For this, I have a question. Is this frequency dependence related to the transfer function of our control servo?
