TABLE III.
Estimates of filter sharpness interpolated from PTCs in the standard (std) and precursor (pre) conditions (left-most column). The level of the signal or “probe” is presented in the column labeled “Lp.” Frequency selectivity is quantified in terms of Q3 and Q10 values and tabulated for each subject (columns).
