The attenuation of frequencies above or below a certain point.
A gradual attenuation of gain-frequency response at either or both ends of the transmission pass band.
The reduction of signal level as the frequency of the signal moves away from the cut-off frequency, especially when the cut-off rate is mild.
Preset attenuation in electronic equipment of a predetermined range of lower frequencies. Used by microphone manufacturers to reduce the proximity effect.
The attenuation that occurs at the lower or upper frequency range of a driver, network, or system. The roll-off frequency is usually defined as the frequency where response is reduced by -3 dB. S-T-U-V
The frequency at which an equaliser, tone control or filter begins to work.
Relates to the attenuation of frequencies, above or below a given point, at a specific rate.
