Frequency Response of LTI Systems

This lecture covers the types and properties of signals and systems, including LTI systems, impulse response, and convolution. It delves into system properties such as linearity, time-invariance, memorylessness, invertibility, causality, and stability. The lecture explains the concept of the impulse response, the Fourier transform, and the frequency response of LTI systems. It also discusses the Laplace and z-transforms, as well as system composition through parallel and series connections. The lecture concludes with a comprehensive overview of the frequency response of LTI systems, including examples of low-pass and band-pass filters, and the implications of frequency selective filters.
