Lecture

Discrete Fourier series: Inherent periodicities and time shifts

Description

This lecture covers the synthesis and analysis formulas of the Discrete Fourier Transform (DFT), mapping N-periodic signals to N-periodic sequences of Fourier coefficients. It explains how the DFT helps define time shifts for finite-length signals, providing insights into circular shifts and the equivalence between DFS and DFT.
