WebThe Iterative Fourier Transform Algorithm (IFTA) is one of the algorithms capable of realizing this synthesis, however, it may lead to stagnation problems when the fields of the Fourier pair exhibit a homeomorphic behavior. To overcome this problem, we use a mapping-type relation for the Fourier pair synthesis. WebFourier transforms connect representations of functions in different domains. By that they enable the selection of modeling and evaluation techniques in the most favorable domain in terms of computation speed and compactness of techniques. draw now free https://perituscoffee.com
