Frequency properties of acoustic emissions from the dry and saturated rock

Different frequency bands (FBs) of acoustic emission (AE) signals from rock fractures contain diverse information about the physical and mechanical properties of a rock. This study proposes a frequency division processing method for the standard description expressions of discrete signals and for de...
