English term or phrase: bin center / side bin
Si parla della funzione di windowing di una scheda elettronica per l'analisi dello spettro dell'onda di pressione. Ecco la frase:

"The configuration constant, BinReject
determines the number of **side bins** rejected from a spectral peak found in the FFT
analysis."

Inoltre:

"The display shows the **bin center** frequency with the
magnitude of the spectral content in peak voltage and psi."

Altra occorrenza:

"Significant
attenuation of FFT magnitude results when spectral content is off the **bin center**."

Se può essere d'aiuto si parla anche di "bin resolution" che è espressa in Herz.

Anyone familiar with this topic?

Explanation:
Vedi ad esempio:
The number of FFT points also gives the frequency resolution, that is how many Hz are represented by a single bar (that is how large the every single bar band filter is). An FFT bar is also called "FFT bin" in literature to emphasize that it contains the energy (or effective voltage) from a frequency range, not a single frequency
You can see it this way: For SR=44100 Hz, a frequency range of 22050 Hz is equally split into 512 bins (or "bars"), every bin is 22050 / 512 = 43.066 Hz wide.
The leftmost bin, this is the one containing the lowest frequency, has only half the width of all other bins. From the example above, the 1st bin covers 0.000 Hz ... 21.5 Hz.
