What Is a Cutoff Frequency?
Sometimes known as a break frequency or corner frequency, a cutoff frequency is a term that is often used in electrical engineering and physics. The term refers to the frequency level at which a device ceases to operate or respond in an efficient manner, effectively causing the device to shut down or cut off. This type of phenomenon is sometimes explained as a reduction of the flow of energy through the device that prevents the consistent function of all the components. When this happens, the device cannot operate at full efficiency, since the necessary power is not present.
