This lecture covers the Discrete Fourier Transform (DFT) applied to signals of unlimited duration. It introduces the concept of limiting signal duration using rectangular windows and discusses the quality of the approximation. The lecture also explores the use of different windows, such as the parabolic and generalized Hamming windows, to improve the accuracy of the DFT. Additionally, it delves into the choice of window length to achieve the desired frequency resolution. Overall, the instructor provides insights into the practical aspects of applying DFT to signals with unlimited duration.
