問題文
A vibration sensor on a pump is configured to sample once every two seconds. The fault the team wants to detect appears as an oscillation that repeats about ten times per second. What outcome should the team expect from this configuration?
選択肢
- The oscillation will be distorted because the sampling interval exceeds the movement period.
- The oscillation will be recorded because the sampling instant captures the true amplitude.
- The oscillation will be ordered because the accurate timestamp fixes the record sequence.
- The oscillation will be recovered because the platform average smooths the adjacent readings.
