Abstract: An upper bound is placed on the number of right half plane zeros of functions of the type $Z - m/n$. $Z$ and $m/n$ are RLC and LC driving point impedance functions respectively. In addition, it is shown that if $\operatorname {Re} Z > 0$ on $j$ axis, the number of right half plane zeros is determined precisely.
