From (1) it follows that y ( z ) has in zk a zero of order not less than vk . Since y ( z ) is holomorphic in the neighborhood of every point of %'K (including z = a), it follows from Hypothesis 6, that y ( z ) vanishes identically in VK. On the other hand, we have for large IzJ of 5. 1 We say tha
Rational interpolants with prescribed poles are used to approximate holomorphic functions on the closure of their region of analyticity under natural assumptions of their properties on the boundary. The transfer functions of some infinite dimensional dynamical systems of interest in applications sat
## Abstract This article presents a method for the interchange of a second‐order circuit with high __Q__‐factor poles by a more complicated network that consists of several low __Q__‐factor stages. The ratio of the substituting circuit transfer function to the given second‐order transfer function a
