Processing distortion phenomenon, also known as signal processing distortion, refers to unwanted alterations or inaccuracies introduced into a signal during its manipulation or transmission by electronic or digital systems. These distortions can manifest in various forms, affecting the fidelity and integrity of the original information. Common types include amplitude distortion, where the relative strength of different frequency components is altered, and phase distortion, where the timing of different frequency components is shifted inconsistently. Nonlinear distortion occurs when the output signal is not a linear function of the input, leading to the generation of new, unwanted frequencies (harmonics and intermodulation products).

In digital signal processing, quantization error is a primary source of distortion. This occurs when an analog signal is converted into a digital representation, and the continuous range of values is mapped to a finite set of discrete levels. Aliasing is another digital distortion that arises when a signal is sampled at a rate too low to accurately capture its highest frequencies, leading to the misinterpretation of higher frequencies as lower ones. These phenomena can significantly impact the perceived quality of audio, images, and other data, and are a critical consideration in the design and operation of communication systems, audio equipment, and imaging devices. Mitigation strategies often involve careful system design, filtering, and the use of higher resolution or sampling rates.
