The method, a variation in the impulse response method, is developed from the frequency response analysis and incorporates the fast Fourier transform. Examples are included showing the application of the method in computing both classic waterhammer and transients in pipes with frequency-dependent ...
Considering the ideal lowpass filter, a time-varying impulse response hI(k, n) can be derived from the inverse DTFT of its frequency response, (7.20)hI(k,n)=12π∫−wc(n)wc(n)1⋅ejωkdw={2πfc(n)π, k=0;sin(2πfc(n)⋅k)πk,k≠0, where k denotes time within...

of simulated activity. Interestingly, we found that instrength-directed traveling waves still emerged in a cortical network model with uniform average time delays suggesting that large-scale traveling wave directions could be robust to specific changes of conduction delays, for example in response ...
response for the reflection spectrum. The filter can be optimized by tuning the internal PUC responses and changing the zero and pole positions57. For the particular case shown in the left part of Fig.3bthe filter yields a notch-type response with 26 dB suppression and a free spectral ...
The disc response is described by its impulse response function (Green's function). The purpose of this work was to gain an understanding of the vibration response and modal behaviour of the disc under conditions where it generates squeal noise due to lateral creepage. The model does not allow...
(1995) have developed an optimized implementation of this Gabor scheme with 1D convolution masks of 11 elements, as the result of a trade–off between fidelity to the frequency response of the channels and low computational cost. In the design of the masks, the filters are forced to be pure...
