This is an App that calculates the cutoff frequency of the current phase shift circuit filter by the user input resistor and capacitor values.
The cutoff frequency is the boundary frequency at which the energy of the output signal of a system begins to drop significantly (in the band stop filter, it rises sharply).
The concept of cutoff frequency is applied to frequency band characteristics such as low pass, high pass, band pass, and band stop in signal transmission channels such as electronic filters.
In addition to the wide application of the concept of cutoff frequency, the concept of cutoff frequency is also used in plasma zone oscillation.
