  • Abstract
    The purpose of this paper is to evaluate the displacement of the zeros pk0 of the impedance Z(p) due to the variations ¿z in the impedance of any network element. It is shown that the displacement is approximately proportional to the mth root of (-¿z) evaluated at p = pk0, where m is the multiplicity of pk0, and the proportionality factor equals the coefficient Ak of (p-pk0)-m in the partial fraction expansion of 1/Z(p).
