Left-top: Raw signal data from the entire sequence of over 40,000 current measurements. Each index position in x-axis corresponds to one measurement in the squiggle. Right-top: Sub-interval of the raw signal data, from position 8000 to 10000. Left-bottom: The current measurements have been transformed by an n.levels = 2 inverse wavelet transformation on positions from 2000 to 2500. Right-bottom: Before applying the inverse wavelet transform, each data point has been recorded twice. The positions are from 4000 to 5000 which directly correlates to the positions in the bottom-left graph
