👉 Distortionless refers to a communication system or process that produces no perceptible changes in the quality of sound, image, or video signals when compared to the original source. It is often used in fields such as music, film, and broadcast television to ensure that the audio and visual content remains consistent across different devices and environments. Distortionless systems can be classified into two categories: non-distortion and distortion. Non-distortion systems do not distort any of the signal components during transmission or processing.
