impulse response

[′im‚pəls ri‚späns]
(control systems)
The response of a system to an impulse which differs from zero for an infinitesimal time, but whose integral over time is unity; this impulse may be represented mathematically by a Dirac delta function.

An average in the frequency domain is determined and this spectral curve is developed into a finite impulse response (FIR) filter.
Impulse response functions in non-linear TVAR model cannot be easily generated from the model parameters as in linear VAR models.
Figure 5 displays the impulse response functions stemming from positive, one-standard-deviation shocks in the above variables.
From the results obtained, it is obvious that the results of measurements in the anechoic chamber and those from impulse responses as well as simulation results show good agreement up to 5 GHz.
For convenience of calculation and expression, the beam antenna gains of transmission node S, destination node D and cooperative node R are equaled into the channel impulse response of each link.
The excitation signal is calculated using impulse response measured at one point of the waveguide.
In this paper, we firstly analyze the impulse response of the maritime multipath channel h(t, [tau]); the power delay profile of the channel is found by taking the spatial average of [[absolute value of h(t, [tau])].
This methodology significantly differs from the one used in the previous studies related to Pakistan, although some studies applied Vector Auto Regressive (VAR/VECM) models, yet their findings are based on error correction term; other studies measured causality among public investment, private investment and output or their results are merely based on impulse response graphs for measuring the nature of effects either positive or negative.
It is based on decimating or interpolating a fixed set of impulse response coefficients.
The impulse response tests were carried out using equipment consisting of a calibrated hammer for exciting an elastic wave by striking the hammer against the surface of the tested material, a geophone and software for data recording and processing (Sadowski, Hola 2013).
Moreover like hhp[n] the impulse response of band stop filter hbs[n] is simply equal to the difference of d[n] and hbp[n].
The impulse response includes a complex gain term, an amplitude or magnitude component which affects the signal strength, and a phase component accounting for the phase shift in the signal.
