  2. Roll-off - Wikipedia

    en.wikipedia.org/wiki/Roll-off

    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. An interesting need for high roll-off arises in EEG machines. Here the filters mostly make do with a basic 20 dB/decade ...

  6. Relative intensity noise - Wikipedia

    en.wikipedia.org/wiki/Relative_intensity_noise

    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 ...

  7. Filter (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Filter_(signal_processing)

    Cutoff frequency is the frequency beyond which the filter will not pass signals. It is usually measured at a specific attenuation such as 3 dB. Roll-off is the rate at which attenuation increases beyond the cut-off frequency. Transition band, the (usually narrow) band of frequencies between a passband and stopband.

    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.
