Cutoff frequency

The frequencies that mark the end of a band or the point at which the characteristics change from a pass to a no-pass band. For example, for an octave filter in a sound level meter centered at 1kHz the lower cutoff frequency will be 707 Hz and the upper cutoff frequency will be at 1,414 Hz. In an idealized filter all other frequencies below and above these two limits will be severely attenuated or completely removed.
