Подскажите, пожалуйста, что такое bin, встречающееся в таком контексте:

During the compensation procedure, some host symbols are moved from one bin to another.

We assume that, for small enough bin-width the distribution of the original cover signal is uniform over the bin, a commonly used assumption in signal compression literature [45].

We have to set a fixed bin-size for the analysis of the statistics when the involved distributions are continuous.

Заранее всем спасибо.
