Cutoff frequency itu apa sih? Jelaskan dalam bahasa sunda ya

Dina élmu fisika jeung téknik listrik, istilah cutoff frequency luhur atawa handap, frékuénsi juru, jeung bréak frequency ngagambarkeun hiji wates dina réspon frékuénsi hiji sistem di mana énergi nu asup kana sistem kasebut mimiti diaténuasi atawa malah dipantulkeun lain ditransmisikeun. Conto umumna:

a cutoff frequency of an idéal lowpass, highpass, bandpass or Band-stop filter, i.e. discrete point in the magnitude transfer function, a frequency where a passband and a stopband meets.

the passband frequency limits of an electronic circuit such as a filter or an amplifier, i.e. the point in the filter specification where the transition band and the passband meets; defined as the 3 dB cutoff frequencies, i.e. the lowest or the highest frequency for which the output of the circuit deviates less than typically 3 dB from the nominal passband value.

the stopband corner frequencies or limit frequencies of a filter, i.e. the point where the transit band and the stopband meets; either the lowest or the highest frequency for which the attenuation is larger than the required stopband attenuation, which for example may be 30 dB or 100 dB.

the upper or lower 3 dB cutoff frequencies of a communication channel. In the case of a waveguide or an antenna, this corresponds to the lower and upper cutoff wavelengths respectively.

the 3 dB cutoff frequency of a signal spectrum, for example of a baseband signal or a passband signal.

The cutoff frequency can also refer to the plasma frequency, or to some concepts related to renormalization in quantum field theory.
