windowing
In digital signal processing, this term refers to a mathematical operation used to minimize spectral leakage by tapering the edges of a finite segment of a signal. It is a technical term of art, typically used in engineering and physics contexts to describe the application of functions like the Hamming or Hanning windows.
In computing and architecture, the term shifts from mathematical analysis to spatial limitation. In UI design, it describes the restriction of a view to a specific viewport, while in construction, it refers to the physical installation process. Because it is primarily used as a gerund or a technical process name, it is almost always treated as an uncountable noun.
Ý nghĩa
The process of dividing a signal or a data set into smaller, overlapping or non-overlapping segments to analyze them in the frequency domain.
A technique in computer graphics and user interface design where a specific portion of a larger image or screen is displayed within a defined boundary.
