1 This is one of the harder things to get right in a system because it infers strong requirements gathering and strong design that correctly interprets the requirements. 2  This is where good System Architects, Business Analysts and Project Managers earn their keep.
The Mid Range The Mid Range band of frequencies covers two octaves from 500 Hz to 2 kHz. This range can give a horn-like quality to instruments (500 Hz to 1 kHz) and a tinny sound (1 kHz to 2 kHz) or a telephone-like quality (all of the range). Equalization usually centers around 800 Hz and 1,.5 kHz.overing about 1.5 octaves, from 80 Hz to 250 Hz, this range of frequencies determines the fatness and fullness of the instrument's sound. Equalization is usually applied centered around two frequencies, 100 Hz and 200 Hz. For guitars and bass, the 100 Hz range tends to add body and fullness.
The mid-range is rarely used in practical statistical analysis, as it lacks efficiency as an estimator for most distributions of interest, because it ignores all intermediate points, and lacks robustness, as outliers change it significantly.Indeed, it is one of the least efficient and least robust statistics.n the middle of these is the midhinge, which is the 25% midsummary. The median can be interpreted as the fully trimmed (50%) mid-range; this accords with the convention that the median of an even number of points is the mean of the two middle points.
