ячейка гармонической составляющей/гармоники
Похоже, у них для каждой гармоники своя ячейка, для которой измеряется эфф. значение.
Такие bin'ы есть в стандарте IEC 61000-4-30, цитаты
из ст. 5.10.1
– or the root of the sum of the squares of the 4 nearest 10/12-cycle r.m.s. value
interharmonic bins (for example, a 316,67 Hz ripple control signal in a 50 Hz power system shall be approximated by a root of the sum of the squares of 310 Hz, 315 Hz, 320 Hz and 325 Hz bins, available from the DFT performed on a 10/12 cycle time interval)
The first method is preferred if the user-specified frequency is in the center of an DFT bin.
The second method is preferred if the frequency is not in the center of a bin.

элемент (частота) дискретизация / элемент разрешения гармоники
три варианта,
1. элемент дискретизации (частота дискретизации)
2. двоичное значение
3. элемент разрешения / столбец

For example, if a voltage waveform is comprised
of 60 Hz and 200 Hz signals, the FFT
cannot directly see the 200 Hz. It only knows 60, 120, 180, 240
,..., which are often
called “bins”. The result would be that the energy of the 200 Hz signal would appear
partially in the 180Hz bin, and partially in the 240 Hz
bin. An FFT-based
processer
could show a voltage value of 115V at 60 Hz, 18 V at the 3rd harmonic, and 12 V at the
4th harmonic, when it really should have been 30 V at 200 Hz. A spectrum analyzer
can also exhibit a similar problem, as it places the energy in its own machine-dependent
bins. In addition, a spectrum analyzer takes only a
snap-shot in time of the harmonics,
which are best analyzed on an averaged, steady-state waveform. http://dranetz.com/wp-content/uploads/2014/02/harmonics-unde...

An Harmonic is a waveform whose frequency is a multiple of the fundamental frequency.
Discussion
In this paper we have proposed a method for estimation instantaneous amplitudes of pitch harmonics with appli-cation to speech signals. The algorithm employs Harmonic Transform as a spectral analysis tool in order to provide the analysis in harmonic domain. As pitch frequency is a time-varying speech parameter proposed technique allows for tracking pitch frequency changes within a single analysis frame. In order to estimate a time-varying amplitudes of a pitch harmonics we have separated an individual harmonics first by selecting only these harmonic spectrum bins which are connected with particular harmonic and then applied the Inverse Harmonic Transform to obtain a signal of each harmonic
