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, ...

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 ...

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 ...

Some people claim that π equals 0 in the complex number system, but this statement is often misunderstood or taken out of context. This explanation clearly breaks down where the idea comes from, the ...
