Today we will be discussing frequency domain versus time domain. My name is- What’s up everyone? The name is Nick Ben and I’m an engineer here at Keysight and welcome to this episode of What the RF! In the last episode we discussed what a spectrum analyzer or signal analyzer is and the various measurements…

## But what is a Fourier series? From heat flow to circle drawings | DE4

Here, we look at the math behind an animation like this, what’s known as a “complex Fourier series”. Each little vector is rotating at some constant integer frequency, and when you add them all together, tip to tail, they draw out some shape over time. By tweaking the initial size and angle of each vector,…

## What is a Fourier Series? (Explained by drawing circles) – Smarter Every Day 205

– What up? Today we’re gonna talk about waves. This is a circle, you probably knew that. If we were to turn this circle on and watch it go up and down and up and down and trace that motion out, you get what’s called a sine wave, which you know to be important in…

## Coding Challenge #125: Fourier Series

(whistle toots) – Hello, welcome to a coding challenge, Fourier series. So what I am going to program in JavaScript using the p5.js library is exactly this. This is what’s known as a Fourier series. It is a series of wave patterns that when summed up together approximate some other function (sighs). What does that…

## But what is the Fourier Transform? A visual introduction.

This right here is what we’re going to build to, this video: A certain animated approach to thinking about a super-important idea from math: The Fourier transform. For anyone unfamiliar with what that is, my #1 goal here is just for the video to be an introduction to that topic. But even for those of…

## Coding Challenge #130.3: Fourier Transform Drawing with Complex Number Input

(whistling) – Hello it is time for yet another video about the Fourier Transforming epicycles. Now you might be asking yourself, what? Why? I mean what’s wrong with you? What’s this weird, unhealthy obsession you have with Fourier Transform? That’s a good question, I’m not so sure actually>But I do know that there is absolutely…
