Impulse Response and Convolution
Impulse Response If a system is linear and time-invariant (LTI), its input-output relation is completely speci ed by the system’s impulse response h(t). 1. One can always nd the impulse response of a system. δ (t)system h 2. Time invariance implies that shifting the input simply shifts the output. δ (t−τ)system h 3.

Discrete Fourier Transform
sigproc.mit.eduFourier transforms have no periodicity constaint: X(Ω) = X∞ n=−∞ x[n]e−jΩn (summed over all samples n) but are functions of continuous domain (Ω). →not convenient for numerical computations Discrete Fourier Transform: discrete frequencies for aperiodic signals.

For LTI systems an equivalent condi-tion to stability is that the impulse response be absolutely summable (discrete time) or absolutely integrable (continuous time). If an LTI system is causal,

Modeling an Impulse in Simulink
www.uml.eduModeling an Impulse in Simulink INTRODUCTION Often a dynamic system is subject to an impulsive load, such as a blow from a hammer. It is important to be able to model such systems to understand what the response will be. This tutorial will discuss three methods for modeling an impulse in Simulink so that it can be used as the
