Complex number terminology is important in electrical engineering to distinguish a purely imaginary quantity, like the impedance of an ideal inductor, jωL, from the reactance of the inductor ωL.

Abstract: Super-resolution is generally referred to as the task of recovering fine details from coarse information. Motivated by applications, such as single-molecule imaging, radar imaging, etc., we ...

This repository provides a collection of functions for generating, sampling, and analyzing complex exponential signals in both time and frequency domains. It includes implementations of DTFT, DFT, and ...

Figure 4. A snapshot, in time, of two complex numbers whose exponents, and thus their phase angles, change with time. The notion of negative frequency is often troubling to engineers who've spent so ...

This repository contains lecture notes and solved problem sets from Stanford's EE261: The Fourier Transform and its Applications. It covers essential topics like Fourier Series, Fourier Transform, ...

The ringdown phase following a binary black hole merger is usually assumed to be well described by a linear superposition of complex exponentials (quasinormal modes). In the strong-field conditions ...
