PHYS 536 Active Filters Introduction The Low Pass
... Better filter performance can be obtained by including more R-C attenuators. (Each RC attenuator contributes one “pole” to the filter.) Only two RC attenuators can be used with one op-amp, hence better filters have several op amps in series. For example, an 8-pole filter would use 4 op amps. The individ ...

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.
