Foster's reactance theorem
Foster's reactance theorem[′fȯs·tərz rē′ak·təns ‚thir·əm] (control systems) The theorem that the most general driving point impedance or admittance of a network, in which every mesh contains independent inductance and capacitance, is a meromorphic function whose poles and zeros are all simple and occur in conjugate pairs on the imaginary axis, and in which these poles and zeros alternate. |
