NONLINEAR DISTORTION Meaning and
Definition
-
Nonlinear distortion refers to the alteration or modification of the shape of a signal in a manner that is not proportional to the input signal. It is a phenomenon commonly encountered in audio, video, and signal processing systems. When a system or device introduces nonlinear distortion, it affects the accuracy and fidelity of the output signal, often resulting in unwanted artifacts or alterations.
Nonlinear distortion arises due to the inherent nonlinearity of certain electronic components and systems. In such cases, the relationship between the input and output signals is not linear, meaning that changes in the input signal do not produce proportional changes in the output signal. This nonlinearity can cause various types of distortion, including harmonic distortion, intermodulation distortion, and amplitude distortion.
Harmonic distortion occurs when the output signal contains additional frequency components that are integer multiples of the original input signal. Intermodulation distortion refers to the generation of unwanted sum and difference frequency components when multiple signals are present. Amplitude distortion, on the other hand, affects the relative levels of different frequency components and can cause changes in signal shape.
Nonlinear distortion can degrade the quality and intelligibility of audio or video signals, leading to reduced clarity, increased noise, altered timbre, or the presence of unwanted frequencies. It is a challenging aspect to overcome, and engineers employ various techniques such as feedback systems, equalization, and waveform shaping to minimize nonlinear distortion and preserve the accuracy of the original signal.

Etymology of NONLINEAR DISTORTION
The etymology of the term "nonlinear distortion" can be understood by breaking down the two main components of the phrase.
1. Nonlinear: The prefix "non-" in English is used to indicate negation or absence. In this case, it suggests that something is not linear. The word "linear" comes from the Latin word "linearis", meaning "belonging to a line". It refers to something that follows a straight line or has a consistent progression. In various scientific and mathematical fields, "linear" is associated with predictable relationships between variables.
2. Distortion: The word "distortion" comes from the Latin word "distortio", which means "twisting awry" or "perverting". It implies a deviation or alteration from the original or desired state, often resulting in errors, changes, or variability.
