The impulse response method is adopted to identify the modal parameters, and the physical parameters are estimated from the characteristic equation of the mathematical model built.
characteristic equation of differential equation system
This expression is expressed in terms of characteristic rootsof the characteristic equation which is transfered from the differential equation ofcharging circuit of Blumlein line by means of Laplace transform.
The new characteristic equation of circular waveguides is discussed.
Based on the analysis of characteristics of explosive field formed by FAE, characteristic equation is fitted with trial data. Then the range of casualty ranking of FAE is deduced (the power range).
The algebraic condition can be represented by the distribution of the roots of the generalized characteristic equation of the ellipse and parabola (hyperbola).
characteristic equation of difference-equation system
It can be decided system stability depending on the characteristic value of characteristic equation. The calculated results agree with the experimental data.
