... “It was finally agreed not to change the existing ringing voltage requirement in the draft 4 standard (i.e. 40 Vrms “shall” and 55 Vrms “should”) but to add requirement that ringing should be superimposed on minimum 15 Vdc.” Accordingly, the new draft, TR41.1.1/05-08-005-R1, states: ...

PRELAB 12: ACTIVE FILTERS
... A low-pass filter has a constant gain (=Vout/Vin) from 0 Hz to a high cut off frequency fH. This cut off frequency is defined as the frequency where the voltage gain is reduced to 0.707, that is at fH the gain is down by 3 dB; after that (f > fH) it decreases as f increases. The frequencies between ...

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.
