Video Overview
This lecture focuses on the Discrete-Time Fourier Transform (DTFT) of the unit step function u[n], a classic and conceptually rich problem in signal processing. We explain why direct computation using limits is not valid and introduce a correct approach using even and odd decomposition. The lecture also addresses how to work with non-absolutely summable signals and manage discontinuities to derive an accurate DTFT expression, including important delta function terms. This session deepens your understanding of DTFT theory and prepares you for more advanced signal analysis.
