Lecture

DFT Analysis: Solar Spots and Daily Temperature

Description

This lecture covers the analysis of solar spots and daily temperature using Discrete Fourier Transform (DFT). It explores the sunspot number calculation, DFT main peaks, and temperature variations over time. The instructor explains how to interpret DFT coefficients and label the frequency axis in the context of real-world examples like train whistles.
