A distortion is the alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation. Distortion is usually unwanted, and often many methods are employed to minimize it in practice. In some fields, however, distortion may be desirable; such is the case with electric guitar distortion.
The addition of noise or other extraneous signals (hum, interference) is not considered to be distortion, though the effects of quantization distortion are sometimes considered noise. A quality measure that explicitly reflects both the noise and the distortion is the Signal-to-noise-and-distortion (SINAD) ratio.
In telecommunication and signal processing, a noise-free "system" can be characterised by a transfer function, such that the output Failed to parse (Missing texvc executable; please see math/README to configure.): y(t)
When the transfer function comprises only a perfect gain constant A and perfect delay T
the output is undistorted. Distortion occurs when the transfer function F is more complicated than this. If F is a linear function, for instance a filter whose gain and/or delay varies with frequency, then the signal will experience linear distortion. Linear distortion will not change the shape of a single sinuosoid, but will usually change the shape of a multi-tone signal.

Distortion
Distortion
Eyes are clean eyes are clones
You were leased now now you're owned
Rats are reeling in your pool
Brats are breeding in your school
Filthy swine everywhere
No they don't really care
Television isn't real
Telling you how to feel
(Chorus)
It's distortion
Distortion
Distortion
Distortion
Saw the angels came to play
Come to wah your fears away
Superman will save the day
But there's a priest you have to pay
Wolves are gnawning at your heels
And it's hard to make a deal
Is there something I could do
Coz you haven't got a clue
(Repeat chorus)
(Bridge)
They will tell you that you're wrong
They will make you pay along
They will tell you that you're through
Still they want a piece of you
