title: A New Effectivemethod to Determine the Discrete Finite Real Signalenvelopes Based on The Parametric Discrete Fourier Transform of the Second Type
abstract: The article shows that expanding the applicationscope of digital signal processing (DSP) systems, increasing the scale of tasks and problems solved by such systems, led to the need to develop a theory,improve DSP methods and algorithms, including those based on discrete finite Fourier and Hilbert transforms (DFT) and (DPG). DFT and DPG, due to their properties, the emergence of the fast Fourier transform (FFT) algorithm (Cooley J.W., Tukey J.W., 1965), have found the widest application in DSP sy
