Question

Hello I need help with this question and I want the correct answer for this question :

The question is as the following

Explain what “saturation arithmetic” is. Why is it important to use in digital signal processing applications?

Answer 1

Answer:

Saturation arithmetic is a form of arithmetic in which all operations, for example, expansion and increase are restricted to a settled range between a base and greatest esteem.

On the off chance that the aftereffect of an activity is more noteworthy than the most extreme, it is set ("braced") to the greatest; on the off chance that it is underneath the base, it is clipped to the base. The name originates from how the esteem moves toward becoming "immersed" when it achieves the extraordinary qualities; further augmentations to a most extreme or subtractions from a base won't change the outcome.

Saturation Arithmetic empowers productive calculations for some issues, especially in digital signal processing. For instance, modifying the volume dimension of a sound signal can result in a flood, and saturation makes fundamentally less mutilation the sound than fold over.

Saturation arithmetic operations are accessible on numerous cutting-edge stages, and specifically was one of the augmentations made by the Intel MMX stage, explicitly for such signal processing applications. This usefulness is additionally accessible in more extensive forms in the SSE2 and AVX2 whole number guidance sets.
