The Fourier transform (FT) is a fundamental technique for analysing signals that are generally dependent on time or space, although any other parameters are possible. It transforms a signal from the ...

In this article we will study the spectral properties of a deterministic signal exponentially damped in the past and in the future (the damping in the future is controlled by a time constant). The ...

When it comes to mathematics, the average person can probably get through most of life well enough with just basic algebra. Some simple statistical concepts would be helpful, and a little calculus ...

The Fourier transform underpins so much of our technological lives, in most cases probably without our realising it. The ability to mathematically split a waveform into its frequency components and ...

Segmentation of medical images is crucial to analyzing anatomical and pathological structures for accurate diagnosis and treatment planning. Various imaging modalities – X-ray, PET, CT, MRI, and US – ...
