kvantálásnál

Kvantálásnál is a Hungarian term that translates to "quantization" in English, referring to the process of converting a continuous range of values into a discrete set of values. This is a fundamental concept in digital signal processing and data compression.

In digital audio, for example, the amplitude of a sound wave is continuously varying. Kvantálásnál involves measuring this amplitude at regular intervals and assigning it to the nearest value from a predefined set of levels. The number of levels available, determined by the bit depth, dictates the precision of this conversion. A higher bit depth means more quantization levels and thus a more accurate representation of the original signal, but also a larger data size.

Similarly, in digital image processing, the color or intensity of each pixel is represented by a numerical value. Kvantálásnál discretizes these values. For instance, an image with 256 possible shades of gray per pixel has undergone quantization. This process is crucial for storing and transmitting information digitally, as continuous analog signals cannot be directly represented by computers. The trade-off in kvantálásnál is between the fidelity of the representation and the amount of data required. Oversampling and techniques like dithering can be employed to mitigate the audible or visible artifacts introduced by quantization.
