EXAMPLE OF POSITIVE FEEDBACK
... Feedback can be voltage or current, negative or positive. Negative voltage feedback decreases gain, and is used to reduce distortion, flatten frequency response, increase input impedance, decrease output impedance. Negative current feedback increases output impedance, and is used in some solid-state ...

Ringing artifacts
In signal processing, particularly digital image processing, ringing artifacts are artifacts that appear as spurious signals near sharp transitions in a signal. Visually, they appear as bands or ""ghosts"" near edges; audibly, they appear as ""echos"" near transients, particularly sounds from percussion instruments; most noticeable are the pre-echos. The term ""ringing"" is because the output signal oscillates at a fading rate around a sharp transition in the input, similar to a bell after being struck. As with other artifacts, their minimization is a criterion in filter design.
