ABSTRACT:
In some embodiments, an apparatus and a system, as well as a method and an article, may include selecting a plurality of signal thresholds T(i)=i*(TMAX/N) for i=2 to N comprising a positive integer greater than one. TMAX may be equal to AMAX/R, where AMAX=a maximum peak amplitude of a signal, such as an acoustic borehole signal, and R=a root-mean-square amplitude of the signal. Applying the plurality of signal thresholds T(i) to the signal to determine a corresponding plurality of peak amplitudes A(i) and signal travel times for selected ones of the plurality of signal thresholds T(i) may also be included.
