cutoff frequency

cutoff frequency

[′kət‚ȯf ‚frē·kwən·sē]
(electronics)
A frequency at which the attenuation of a device begins to increase sharply, such as the limiting frequency below which a traveling wave in a given mode cannot be maintained in a waveguide, or the frequency above which an electron tube loses efficiency rapidly. Also known as critical frequency; cutoff.
