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 $ {\mathop{\rm Re}\nolimits} Z > 0$ on $ j$ axis, the number of right half plane zeros is determined precisely.
