Before this measurement, it would be silent run
2025/04/10 6:38:00 - 07:48:00 Acoustic injection PSL room
Excitation : K1:PEM-EXCITATION_MCF0_RACK_13_EXC
50 - 400 Hz , 1Hz resolution, 10 s in each measurement, 100 cnt
Fig.1. showed the whitening spectrogram
Four IPC glitch like signal detected (17, 31, 37, 59 min)
Large signal detected in 65 min, but it may come from another glitch
We need to test the signal around 12 min and 48 min, but they would also come from another glitch, I think.
2025/04/10 8:49:00 - 08:59:00 Acoustic injection PSL room
Excitation : K1:PEM-EXCITATION_MCF0_RACK_13_EXC
300 - 400 Hz , 2Hz resolution, 10 s in each measurement, 100 cnt
Fig.2. showed the whitening spectrogram
I analyzed the injection data of
2025/04/10 6:38:00 - 07:48:00 Acoustic injection PSL room
Excitation : K1:PEM-EXCITATION_MCF0_RACK_13_EXC
50 - 400 Hz , 1Hz resolution, 10 s in each measurement, 100 cnt
The IPC glitch times are removed from the analysis, but the other glitches-like data is included.
I also analyzed the injection data of
2025/04/10 8:49:00 - 08:59:00 Acoustic injection PSL room
Excitation : K1:PEM-EXCITATION_MCF0_RACK_13_EXC
300 - 400 Hz , 2Hz resolution, 10 s in each measurement, 100 cnt
Here, the glitchy time (248~354Hz injection) is removed.
Appendix: a case of using only 50-300Hz data in the 50-400Hz injection test
