Enhanced processing of low signal-to-noise-ratio dynamic signals from pavement testing
TL;DR: Low-pass filtering and wavelet filtering is explored to de-noise the strain signals for data pre-processing, and the adaptive maximum energy ratio method and standard deviation method are proposed to isolate the foreground loading areas from the background noise of the strain responses.
