In the collection stage, samples for each time period are annotated through manual recording. During the dataset construction phase, the data is partitioned based on the index supplied by the internal data structure within the file. The mechanical wave detection captured a singular signal pulse spanning a duration of 1638.4 microseconds. In accordance with the instrument's sampling interval of 0.2 microseconds, Python was utilized to transfer signal data in the form of a matrix with dimensions 8192×2.
Dataset overview
This dataset can be very huge (192 GB), so it is compressed in zip format.
