Lecture
This lecture covers the concept of impulse response in control systems, defining it as the output of a system in response to a Dirac delta function. It explains how the impulse response characterizes a Linear Time-Invariant (LTI) system and demonstrates the response of an LTI system to an input signal. The lecture also discusses the importance of impulse response in computing the output for any input signal and the limitations of infinitely-long impulse responses, leading to the need for a more compact representation.
