It is especially useful when referring to frequencies and when describing frequency response of electronic systems, such as audio amplifiers and filters. The factor-of-ten in a decade can be in either direction: so one decade up from 100 Hz is 1000 Hz, and one decade down is 10 Hz. The factor-of-ten is what is important, not the unit used, so $3.14 rad/s$ is one decade down from $31.4 rad/s$."^^ ; , , , , , , , ; ; ; "0112/2///62720#UAB338" ; "http://en.wikipedia.org/wiki/Decade_(log_scale)"^^xsd:anyURI ; "dec" ; "DEC" .
