• diffhist Decibel 18:47 −99 Em3rgent0rdr talk contribs (→Examples: Shouldn't say "The unit dBW is often used to denote a ratio" because dBW is treated as an absolute unit, as described later and before in this article. Deleting from here also cause up to this point in the article we are focused on the original dB...instead I'm mentioning the dBW later in "Electronics" when talk about dBm.) Tag: Visual edit

• diffhist Decibel 03:59 +283 Em3rgent0rdr talk contribs (→Reporting large ratios: Since there was a "citation needed" for this example, I'm instead using an example from the previously-cited decilog article of "50 dB" being easier to say than "a power ratio of 10,000 : 1". And the "See Bode plot and Semi-log plot" lacked any explanation of the point, so added description of how Bode plot can be labeled with simple notches every 10 dB instead of labeling with powers of 10 in semi-log.)

Horton and tried to more fully express their point (what was previous written was just quotes out of that article's abstract) and add examples of usage ("mass logit") and introduce this paragraph to work for both logit and decilog.)

• diffhist Decibel 00:38 +292 Em3rgent0rdr talk contribs (Someone recently put "citation needed" for "decibels are necessarily a dimensionless unit". To address this, I'm spelling out a quick proof why: "Ratios are dimensionless since their units cancel out, so the decibel (as a logarithm of a ratio) is necessarily also a dimensionless unit" and deleting the "citation needed" cause this necessarily follows. Next paragraph try to make a better distinction between "strict original usage above" versus "the word decibel has since also been used for".) Tag: Visual edit
