Szukana fraza: [Abstract = "This DFT is calculated with the help of the Fast Fourier Transform \(FFT\) algorithm transformed into the time domain. The result is the cyphert ext in the form of an N\-lag WMRTS. To decrypt the cyphertext, it is processed by the FFT algorithm, the result being the original DFT, from which all phase shifts are recovered. The paper presents theoretical foundations of the method and a numerical example demonstrating its effectiveness."]
