Roll-off is also significant on audio loudspeaker crossover filters: here the need is not so much for a high roll-off but that the roll-offs of the high frequency and low-frequency sections are symmetrical and complementary.

The roll off frequency sets what is specified as the RIN bandwidth. RIN is sometimes referred to as a kind of 1/f noise otherwise known as pink noise. Relative intensity noise is measured by sampling the output current of a photodetector over time and transforming this data set into frequency with a fast Fourier transform. Alternatively, it can ...

1410 AM was the original frequency of Taylorville's primary local station, WTIM, which broadcast at that frequency from its sign-on in 1952 until 1997 when it moved to 97.3 FM (now WRAN; WTIM is now heard on 870 AM). In 1998, 1410 was acquired by Covenant Network as its second station and received new WIHM call letters.
NIU had wanted a second frequency for some time, and finally got it in 1991 when WNIJ signed on at 90.5 FM in Rockford. WNIU became a full-time classical music station, while WNIJ was a more traditional full-service NPR station. In 1998, the two stations swapped frequencies, with WNIJ moving to the stronger 89.5 frequency while WNIU moved to 90.5.
