Abstract: A data analysis system includes a data input interface for receiving a time domain signal, a data segmentation processor that segments the time domain signal into single segments of a predetermined length, a data converter that converts the time domain signal into a spectrum waveform in the frequency domain based on the single segments, a data analyzer that detects a data anomaly in the spectrum waveform, a segment identifier that, if the data anomaly is detected in the spectrum waveform, identifies the segment that causes the data anomaly in the spectrum waveform, and a data output interface that, if the data anomaly is detected in the spectrum waveform, outputs at least one of an indication of the identified segment and the identified segment. The present disclosure further provides a respective measurement device and a respective method.
