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.

Based on Matlab simulation platform, we built the simulation environment and simulated the power line channel impulse response. PLC channel frequency domain response is in 15 paths, and the longest path is 1000 m in the channel model.
At present, many acoustic detection methods are based on impulse response.
And by using the inverse Fourier transform, we can determine the channel impulse response.
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.
where * denotes convolution and T is the duration of the measured cavity impulse response. With the time-delay information reversed, h(T - t) propagates inside the cavity following the same multipath ray trajectories, consequently removing the multipath delays and allowing the waves to focus at the output port to from a compressed short pulse at t = T.
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.
The FRM technique was originally proposed for designing application-specific low complexity sharp transition-band finite impulse response FIR filters.
