IEVref: 351-45-29 ID: Language: en Status: Standard Term: unit-impulse response Synonym1: weighting function [Preferred] Synonym2: Synonym3: Symbol: g(t) Definition: quotient impulse response Δvδ(t) divided by the impulse area Kδ of the impulse function, the quotient described by$g\left(t\right)=\frac{1}{{K}_{\text{δ}}}\cdot \Delta {v}_{\delta }\left(t\right)$Note 1 to entry: The unit-impulse response g(t) of a system contains all properties of the system and is used to calculate the response Δv(t) of the system to any input variable Δu(t) by the convolution integral$\Delta v\left(t\right)=\underset{-\infty }{\overset{\infty }{\int }}g\left(\tau \right)\cdot \Delta u\left(t-\tau \right)\text{d}\tau$.Note 2 to entry: The systems frequency response $G\left(\text{j}\cdot \omega \right)$ may be calculated by Fourier transformation of g(t): $G\left(\text{j}\cdot \omega \right)=ℱ\left\{g\left(t\right)\right\}$.Note 3 to entry: The unit-impulse response of a system mathematically may be considered to result from application of a unit impulse to an input variable.Note 4 to entry: This entry was numbered 351-24-19 in IEC 60050-351:2006.
