distorsi

Distorsi is a term that denotes deviation from an original form across various disciplines. In general, it describes alteration or misrepresentation introduced by a process, medium, or interpretation.

In signal processing and telecommunications, distorsi on is any alteration of a transmitted or stored signal relative to the original. Common types include harmonic distortion, where nonlinear devices add extra harmonics; intermodulation distortion, where mixed frequencies generate new components; and amplitude or phase distortion from nonlinear gain or filter responses. Causes include nonlinear electronics, clipping, bandwidth limits, and imperfect filters. Mitigation uses linear components, careful gain staging, equalization, and distortion compensation techniques.

In acoustics and music, distorsi on can be unwanted or intentional. Unwanted distortion arises from clipping or overload in amplifiers and speakers. Intentional distortion, produced by guitar pedals or amplifiers, alters the waveform to create overdrive, fuzz, or other timbres through controlled clipping and filtering.

In optics, distorsi on refers to deviations from true geometry caused by lenses or projection systems. Barrel and pincushion distortions are common geometric distortions; chromatic aberration is a related but separate wavelength-dependent effect. Corrections rely on lens design, calibration, and software remapping.

In psychology, cognitive distortions are systematic errors in thinking that contribute to negative emotions and maladaptive behavior. Examples include overgeneralization, catastrophizing, and black-and-white thinking. They are addressed in cognitive-behavioral therapy and mindfulness practices.

In media and information, distorsi on describes biased or misleading representations of events or data, which can arise from selective reporting, framing, or manipulation.

Thus, distorsi serves as a cross-disciplinary concept centered on deviation from a reference form, whether in signals, perception, or representation.
