Harmonic analysis occupies a central position in modern mathematical analysis by providing the tools to express complex functions as superpositions of simpler sinusoidal components via the Fourier ...

The Fourier transform of a signal decomposes it into a sum of its various frequency components. However, in the real world a lot of the signals we deal with are either discrete or, even if they are ...

Abstract: In this paper, we define the Windowed Octonion Quadratic Phase Fourier Transform (WOQPFT) and derive its inversion formula, including its essential properties, such as linearity, ...

Researchers have developed a new method to better understand and mitigate quantum noise, which disrupts the operation of qubits. This innovation could enhance the reliability of quantum computing and ...
