>For repetitive (periodical) excitation, resonances due to

enough to
>sufficiently suppress the resonances. The steady-state transfer
>profile may show impedance peaks, which are sometimes even bigger
than the
>impedance magnitude at the excitation point. Consequence: at a
>point, the noise from a given source is bigger than at the source
>This effect was simulated and measured on various structures

>For physically large and/or high-current designs, however,

>resolution may be in the milliohm range. One possible way to achieve such
>measurement resolution was published at DesignCon99 (also available on

        Could you please tell me where I can find (on-line) the articles you
        Thank you!
