Road Noise Reduction Using Transfer Function Synthesis Method
SAE Technical Paper Series, 1993<div class="htmlview paragraph">An experimental simulation method has been developed for predicting the noise and vibration characteristics of a complete vehicle when body frame stiffness is changed. This method was developed by means of an improved transfer function synthesis method.

Method of synthesis of non-minimum-phase transfer functions for time-delay simulation
Radio and Electronic Engineer, 1971The paper presents a new method for designing non-minimum phase rational approximants of the ideal delay function e?s suitable for the applications where the frequency spectrum of the input signal occupies large bandwidth. It is shown by theoretical considerations that for this purpose the most suitable type of delay characteristic is the one ...

SAE Technical Paper Series, 2009
<div class="htmlview paragraph">In order to characterize the noise filtering performance of a vehicle with respect to both structure- and airborne transfer paths, a reciprocal transfer functions synthesis method is proposed. Simple, timesaving and repeatable, the procedure is an interesting alternative to the direct measurement.</div> < ...

Asymptotic behaviour of transfer function synthesis methods
International Journal of Control, 1987This paper presents an analysis of the asymptotic behaviour of the solutions to various iterative linear least-squares methods that synthesize transfer functions from frequency-response data. The methods of Sanathanan and Koerner and Lawrence and Rogers are shown to possess asymptotic solutions that do not coincide with the solution to a fundamental ...

Noise Sensitivity Analysis of an Engine Mount System Using the Transfer Function Synthesis Method
SAE Technical Paper Series, 2001<div class="htmlview paragraph">The transfer function synthesis method is one of the most powerful methods in analyzing the responses of complex built-up structures under high modal density. Its superiority mostly comes from the ability to incorporate experimental FRFs into the formulation.

The recurrent-continuant method of transfer function synthesis
Radio and Electronic Engineer, 1969It is shown that the ratio of input voltage to output voltage for any passive ladder type low-pass filter network is always a polynomial in the complex frequency s. This polynomial can always be written by inspection as a single determinant in the form of a recurrent.

IEEE Transactions on Electromagnetic Compatibility, 2010
This paper presents a method to construct a transfer function (TF) of the pulse-forming network by using the latent-roots method for modeling the electrical fast transients/burst (EFT/B) generator. In the TF, two negative real roots characterize the nonoscillation process of the network, while one complex-conjugate pair characterizes the damping ...

A general method was developed for the preparation of 1-functionally-substituted spiro-[2,4]hepta-4,6-dienes in 50–95% yield by the reaction of cyclopentadiene and the corresponding substituted 1,2-dibromoethanes under phase transfer catalysis conditions.

Journal of Macromolecular Science, Part A, 2003
A modified method with respect to an earlier conventional procedure was successfully attempted and we now report the new procedure for the synthesis of surface-grafting technique by the delayed addition of inexpensive vinyltoluene (VT) functionality to the partially polymerized supporting monomers viz., styrene (St) and divinylbenzene (DVB) via ...
