Why we can’t extract precise time and frequency information from a time series mutually, and how wavelet analysis can tackle this limitation
1. Introduction
The connection between the Fourier Transform, Uncertainty Principle, and time series analysis unveils a fascinating interplay that shapes the extraction of simultaneous temporal and frequency information. To understand this relationship, it's important to first briefly understand what a Fourier Transform (FT) and the uncertainty principle are as a consequence. Then, …
