Fourier transforms are mathematical calculations that can be used to identify the frequencies that make up a signal and shed ...

Fractional transforms extend classical integral transforms by introducing a continuous parameter that governs the interpolation between time and frequency domains. The fractional Fourier transform ...

A key algorithm that quietly empowers and simplifies our electronics is the Fourier transform, which turns the graph of a signal varying in time into a graph that describes it in terms of its ...

Bivariate signals, representing vector motions in 2D spaces (e.g., oceanography and radar systems), require specialized uncertainty analysis beyond traditional complex signals. This paper introduces ...

A new review of 201 studies traces how bridge structural health monitoring evolved from classical Fourier and wavelet ...
