## 4. Visualization of the Complex Fourier Series

Fourier Series Classically Chapter 4. Visualization of the Complex Fourier SeriesChapter 4.1 Visualization toolIt is generally available and comes from https://betterxplained.com/articles/an-interactive-guide-to-the-fourier-transform. It’s easier to understand the Complex Fourier Series equation with real part in Fig. 3-12 in Chapter 3. And from there it is very close to the general equation for the Complex Fourier Series from …

## 3. Complex Fourier Series

Fourier Series Classically Chapter 3 Complex Fourier Series Chapter 3.1 The complex function exp(jωt) as a rotating vector In automatics, electrical engineering and many other fields, the complex function exp(jωt) appears all the time. This is a special case of a complex function whose domain is a real number time t, not any complex number …

## 2. Trigonometric Fourier Series

Fourier Series Classically Chapter 2 Trigonometric Fourier series Chapter 2.1 Introduction Let us decompose into a Fourier Series the function f(t) with period T=2π/sec corresponding to the pulsation ω=1/sec. For now, take these formulas on word of honor. Fig. 2-1 Decomposition of the function f(t) on a Fourier Series where: a0-constant component 1ω– pulsation of …

## 1. Introduction

Fourier Series Classically Chapter 1 Introduction It is also an introduction to the next courses “Fourier Transform” and “Laplace Transform”. The latter will appear in the future. Chapter 1.1 Any time function f(t) can be decomposed into sine waves! Maybe not every*, but let’s not be petty. It is easiest when we are dealing with …
