Signal thresholding apparatus, systems, and methods |
摘要 |
In some embodiments, an apparatus and a system, as well as a method and an article, may include selecting a plurality of signal thresholds including a product of an integer ranging from about 2 to N and a ratio of a quotient of a maximum peak amplitude of the acoustic borehole signal and a root-mean-square amplitude of the acoustic borehole signal, to N. Applying the plurality of signal thresholds to the acoustic borehole signal to determine a corresponding plurality of peak amplitudes and signal travel times for selected ones of the plurality of signal thresholds may also be included.
