The Gibbs phenomenon is undesirable because it causes artifacts, namely clipping from the overshoot and undershoot, and ringing artifacts from the oscillations. In the case of low-pass filtering, these can be reduced or eliminated by using different low-pass filters.
The main cause of ringing artifacts is overshoot and oscillations in the step response of a filter.. The main cause of ringing artifacts is due to a signal being bandlimited (specifically, not having high frequencies) or passed through a low-pass filter; this is the frequency domain description.
Gibbs artifact (T1 sagittal study of the brain). [1] Gibbs artifacts or Gibbs ringing artifacts, also known as truncation artifacts are caused by the under-sampling of high spatial frequencies at sharp boundaries in the image. [5] [6] Lack of appropriate high-frequency components leads to an oscillation at a sharp transition known as a ringing ...
In signal processing, overshoot is when the output of a filter has a higher maximum value than the input, specifically for the step response, and frequently yields the related phenomenon of ringing artifacts. This occurs for instance in using the sinc filter as an ideal low-pass filter.
In electrical circuits, ringing is an oscillation of a voltage or current.Ringing can be undesirable because it causes extra current to flow, thereby wasting energy and causing extra heating of the components; it can cause unwanted electromagnetic radiation to be emitted [citation needed]; it can increase settling time for the desired final state; and it may cause unwanted triggering of ...

Ringing artifacts around the edges of the pulse are heavily accentuated (Gibbs phenomenon) and the signal distorts as it propagates, even in the absence of a dispersive medium. This artifact is a direct result of the discretization scheme.
The following contains spoilers from the Feb. 19 episode of CBS’ NCIS. We at long last have a 10-20 on one Leroy Jethro Gibbs, more than two years after Mark Harmon’s character was last seen ...
