Distortion is the alteration of the original shape or characteristic of a signal, such as an audio or video signal. Learn about different types of distortion, such as amplitude, harmonic, frequency and phase distortion, and how they affect signal processing and communication. Various types of distortion exist, including harmonic distortion, intermodulation distortion, and frequency distortion. Harmonic distortion occurs when additional harmonics are introduced to the original signal, often due to non-linear effects in audio equipment. A distortion is a change, twist, or exaggeration that makes something appear different from the way it really is. You can distort an image, a thought, or even an idea. To say that I never take out the garbage is a distortion of the facts.
