distortion, in acoustics and electronics, any change in a signal that alters the basic waveform or the relationship between various frequency components; it is usually a degradation of the signal.
This is mainly caused by the phenomenon of reduction in inductance in the conductor due to the skin effect. This is the frequency distortion that the signal receives from the transmission line.
In the art world, a distortion is any change made by an artist to the size, shape or visual character of a form in order to express an idea, convey a feeling, or enhance visual impact.
To overcome the effects of attenuation distortion, communications circuits have special equalization equipment attached at the ends of the circuit or in between, designed to attenuate the signal evenly across the frequency spectrum, or to allow the signal to be received at equal amplitude for all frequencies.
Technically distortion is ANY deviation in the shape of an audio waveform between two points in a signal path. Given that understanding, just about any audio process (equalization, compression) are all forms of distortion.
A melted crayon, a deflated balloon, a CD or DVD with scratches that no longer plays correctly — these things have all been affected by distortion. Other examples of distortion are things like your reflection in a broken mirror or the sound of your voice underwater.
There are four main types of distortion that come from map projections: distance, direction, shape and area.
There are three main types of transmission impairment: signal distortion, attenuation, and noises. The three main reasons for signal distortion in transmission impairment are environmental parameters, properties of the transmission medium, and distance between the transmission end and receiving end.
The distortions occurring in the transmission line are called waveform distortion or line distortion. Waveform distortion is of two types: a) Frequency distortion b) Phase or Delay Distortion.
There are three types of transmission impairments: attenuation, delay distortion, and noise.
You can use tools like noise reduction, normalization, compression, EQ, and limiter to improve your sound quality and reduce distortion. Noise reduction can help you remove unwanted background noise or hum. Normalization can help you balance the volume of your audio.
Two common types of distortion. In barrel distortion (left), magnification decreases with distance from the centre of the image; in pincushion distortion (right), magnification increases with distance.
Distortion refers to the altering or deformation of an audio signal's original waveform. Technically, any kind of audio processing (EQ, compression, time-based effects, etc.) alters an audio signal, but in audio production, the term is used to describe either intentional or undesired sonic destruction.
Distortion in a signal is the alteration or change of the shape or some other characteristic of the waveform. In contrast, noise is an external random signal added to the original signal. It's harder to remove the effects of noise than to remove the effects of distortion.
Frequency distortion: This occurs when a circuit or device causes the voltage/current of different frequency components in an input signal to be modified by different amounts. This can only be seen on broadband signals. This generally occurs in filters when the magnitude of the Bode plot is nonlinear.
The most occurring type of shunt faults is Single Line-to-ground faults (SLG), which one of the four types of shunt faults, which occur along the power lines. This type of fault occurs when one conductor falls to ground or contacts the neutral wire. It could also be the result of falling trees in a winter storm.
There are five basic distortions of this kind: (1) animation; (2) fast motion; (3) slow motion; (4) reverse motion; and (5) freeze frames.
Harmonic distortion may be measured by looking at the output spectrum on a spectrum analyzer and observing the values of the second, third, fourth, etc., harmonics with respect to the amplitude of the fundamental signal. The value is usually expressed as a ratio in %, ppm, dB, or dBc.
In functional analysis, a branch of mathematics, the distortion problem is to determine by how much one can distort the unit sphere in a given Banach space using an equivalent norm.
While EQ can increase the amplitude of frequencies that exist in a sound, harmonic distortion adds frequencies that didn't exist in the original sound. The right amount of these new frequencies can actually enhance the clarity of a sound and bring it forward in a dense mix.
It's very simple to do once you know how to do it: you create with an eq a narrow notch and boost it considerably, around 6/10db, then you start sweeping left and right through your distorted guitar and bass sound.
Unwanted distortion is caused by a signal which is "too strong". If an audio signal level is too high for a particular component to cope with, then parts of the signal will be lost. This results in the rasping distorted sound.
When a signal travels through a medium, it loses some of its energy due to the resistance of the medium. This loss of energy is called attenuation. When a signal travels through a medium from one point to another, it may change the form or shape of the signal. This is known as distortion.
