    Chapter 6. INTERNAL PROCESSING 6 - 5 Noise Protection Function This unit distinguishes intrusive noise, such as electromagnetic or impact waveforms, from acceleration signals, as shown in the figure below.

INTERNAL PROCESSING z Zero-cross noise detection (ZCN) In this detection method, if an AC acceleration for calculation having a long period occurs, which is not normal for vibration waveforms like those of an earthquake, it is judged to be zero-cross noise.
