Standards for Reporting EMG Data
... There are several methods of EMG processing. Smoothing the rectified signal with a low pass filter of a given time constant (10-250 ms) is often described as "smoothing with a low pass filter with a time constant of x ms". Time constants higher than 25-30 ms introduce detectable delays and should b ...

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.
