Distortion

Distortion refers to an alteration or deformation of a signal, image, or sound from its original form. It occurs when the output differs from the input due to factors like equipment limitations, interference, or processing errors. In audio, distortion can make music sound harsh or fuzzy; in images, it might cause shapes to appear warped. While some distortion is intentional (like in artistic effects), unwanted distortion can reduce quality or clarity. Essentially, distortion is a change that moves the original content away from its true, intended form, impacting how accurately it is perceived or reproduced.
