It is shown that the calculation of the IDFT for lowpass equivalent responses of passband frequency response
measurements is obtained by two equivalent algorithms, which are denoted by Eqs.

In 20-100 Hz full frequency range, the acoustic characteristic curve to a great extent retains peak frequency features of conventional FEM frequency response

curve of the system with optimum values of absorber parameters for the viscoelastic and elastic blade respectively.
The complex frequency response
of such ideal line connected between the source of oscillations with internal impedance [Z.sub.S] = [Z.sub.L] is calculated by the formula
Let us split the model frequency response
in two parts, the (unknown) generic kth harmonic oscillator and the (unknown) residual part [W.sub.res], as follows:
Figure 3 describes the magnitude of the frequency response
in case of rectangular window as a function of its width K.
Figure 11 shows the simulated frequency response
of the broadband band-pass filter designed using a MMR resonator in the workspace of ADS versus return losses (S11) and insertion losses ([S.sub.21]) in a range of 0-16 GHz.
Three models for the frequency response
The received signal vector y and the channel frequency response
vector h are provided as input to the four receiver processing blocks (RPB) along with precomputed data vectors [d.sup.(1)], [d.sup.(2)], [d.sup.(3)], and [d.sup.(4)].
The on-line FRA method has been implemented through an Impulse Frequency Response
