← ScienceWhich outcome impairs accelerometer accuracy when subject to vibrations?
A)Increased signal phase noise floor
B)Reduced capacitive sensing resolution
C)Mechanical resonance causing aliasing
D)Nonlinear frequency mixing via intermodulation✓
💡 Explanation
Intermodulation generates new frequency content from vibration harmonics, where these mix to create false signals that add noise because they distort the accelerometer's output, therefore accuracy is degraded, rather than phase shifts or resonance alone.
