Signal Reconstruction: Sampling Theorem 2

This lecture covers the reconstruction of a signal from its sampled version, exploring techniques such as connecting points and finding polynomials passing through them. It delves into general interpolation formulas for signals, emphasizing the importance of functions in the process. The instructor highlights the challenges of polynomial interpolation, including complexity and instability when points are altered. The lecture concludes by discussing the implications of specific conditions on interpolation functions, ensuring accurate signal reconstruction.
