Patent ID: 8154311

Claim:
A method for characterizing the linear properties of an electrical component having n>1 ports (p 1 , . . . , p n ), said method comprising: determining, in an estimation procedure, an estimated admittance matrix Y′ of said component by applying voltages to said ports (p 1 , . . . , p n ) and measuring a response of said component, determining eigenvectors v k of said estimated admittance matrix Y′; determining voltage patterns u k corresponding to the determined eigenvectors v k such that the voltage patterns u k are substantially proportional to at least one of the determined eigenvectors v k ; applying, in a measurement procedure, approximately the determined voltage patterns u k to the ports (p 1 , . . . , p n ) of said component; and determining, in the measurement procedure, based on each applied voltage pattern u k , a response of said component.
