[Siemens GTO-VVVF] DB Class 411/415 (ICE T) [Inductor recorded]

Modulations at acceleration (from my analysis):
1. Asynchronous: 100Hz
2. Asynchronous: 300Hz to 325Hz
3. Synchronous: 11 Pulse
3. Synchronous: 9 Pulse
4. Synchronous: 7 Pulse
5. Synchronous: Wide-7 Pulse
6. Synchronous: Wide-5 Pulse
7. Synchronous: 5 Pulse
8. Synchronous: Wide-3 Pulse
9. Synchronous: 1 Pulse
On the deceleration, there is an additional Synchronous 13-Pulse mode before going to Asynchronous.
Edit(16.05.24): I plan to reupload this recording with waveform soon.
Softwares used: Sonic Visualizer, Audacity, Adobe Premiere Pro
Filters applied: Low-Pass Filter (5 kHz)
Recorder: Zoom H1n
Inductor: Cochlear Nucleus 7 (CP1000) [in Telecoil mode]
Inductance: unknown (presumably more than 100mH)
