Response of a fuzzy structure in terms of the impulse response function

The Journal of the Acoustical Society of America, 1995
A masterstructure is defined in terms of a known and proper impulse response function g∞(x‖x’,ω), where x is the spatial variable that spans the master structure and ω is the frequency variable. The response v∞(x,ω) of the master structure to the external drive pe(x,ω) is stated in the form v∞(x,ω)=∫g∞(x‖x’, ω)dx’ pe(x’,ω), where dx is an elemental ...

Properties of impulsive responses and Green's functions

IRE Transactions on Circuit Theory, 1955
THE INVESTIGATION of general communication systems usually starts by considering a black box, N, with an input u and an output v (see Fig. 1). We express the relation between u and v symbolically by the equation $v = N_u. \eqno{\hbox{(1)}}$ (1)

Impact of SAR impulse response function in interferometric measurement

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
The stable point network (SPN) is a persistent scatterer interferometric technique developed by ALTAMIRA INFORMATION in 2001. The technique makes use of both ERS SAR and/or ASAR differential phase measurements to generate long term terrain movement and precise height maps with the same resolution as the original SAR images.

Efficient and Accurate Calculation of Discrete Frequency Response Functions and Impulse Response Functions

Volume 8: 27th Conference on Mechanical Vibration and Noise, 2015
Modal properties of a structure can be identified by experimental modal analysis (EMA). Discrete frequency response functions (FRFs) and impulse response functions (IRFs) between responses and excitation are bases for EMA. In calculation of a discrete FRF, discrete Fourier transform (DFT) is applied to both response and excitation data series, and a ...

Errors involved in computing impulse response functions via frequency response functions

Mechanical Systems and Signal Processing, 1992
Abstract This paper discusses the errors that are introduced when calculating the impulse response function from the frequency response function using DFT/FFT analysis technique. The impulse response function is used in many applications of system analysis where a description of the system characteristics is preferred in the time domain rather than ...

Transformation function of the external ear in response to impulsive stimulation

The Journal of the Acoustical Society of America, 1974
Impulse noise presents great difficulties in the estimation of auditory hazard. As a first step in determining the energy that actually reaches the cochlea during impulsive stimulation, the transformation function of the external ear was measured in response to impulsive stimulation. A model of the human external ear and live cat ears instrumented with
