Intuitive Guide to Fourier Transform and the Spectrum: 9783031278921: Langton, Charan, Levin, Victor

This book provides a comprehensive introduction to Fourier analysis, covering both the theoretical and practical aspects of the subject.

The authors take a step-by-step approach, starting with the Fourier series and progressing to more advanced topics such as the Fast Fourier Transform (FFT).

The book includes numerous examples, detailed explanations, and plots to help readers understand difficult concepts and apply them to real-world problems.

The authors also cover the application of Fourier analysis to random signals and how to assess their spectral distribution using Parseval's and Wiener-Khintchine-Einstein theorems.

Additionally, the book provides guidelines for creating low-variance, low-bias spectra using windows and ACF truncation.

With its clear explanations and practical examples, this book is an excellent resource for students and professionals looking to gain a deeper understanding of Fourier analysis and its applications in data analysis.
