WebThe Unit Impulse Function. In discrete time systems the unit impulse is defined somewhat differently than in continuous time systems. The Z Transform is given by. From the definition of the impulse, every term of the summation is zero except when k=0. So. Note that this is the same as the Laplace Transform of a unit impulse in continuous time. WebThe idealized impulsive forcing function is the Dirac delta function * (or the unit impulse function), denotes δ(t). It is defined by the two properties δ(t) = 0, if t ≠ 0, and ∫ ∞ −∞ δ(t)dt=1. That is, it is a force of zero duration that is only non-zero at the exact moment t = 0, and has strength (total impulse) of 1 unit.

System Output. Figure 4.2. 1: We can determine the system's output, y [ n], if we know the system's impulse response, h [ n], and the input, x [ n]. The output for a unit impulse input is called the impulse response.
