Lecture
This lecture covers the response to various types of inputs, including sinusoidal, periodic, and complex sinusoidal excitations. It delves into the frequency response of systems, sampling theorem, ideal filters, and linear phase filters. The lecture also discusses Fourier series, impulse response, BIBO stability condition, and explicit methods for finding responses to excitation. Additionally, it explores ideal filters like the low pass and bandpass filters, as well as the concept of linear phase. The importance of understanding these concepts for system analysis is emphasized.
