This paper investigates the cascade synthesis of the lossless network double-end loaded with resistance. The concept of zero-pole distributive chart of the input impedance is defined. Hence is derived a new and much stricter proof of Fialkow's LC ladder synthesis theorem. A series of problems involved in the LC synthesis are discussed in detail. Combining the realization of the complex transfer zeros given in Documents (1) (2) with Fialkow's realization of the real frequency transfer zeros, the author proposes a design of a double-end loaded cascade lossless network, which employs so far the fewest Oarlington-D.C. sections.

But it is not always the case in practice. Owing to the uninterrupted development of electronics, it is increasingly conspicuous to develop the realization theory of transfer function of the network composed of single or/and two-port arbitrary RC terminations.

In general, the realization theory of two-port RC network is still based on the assumption that both the input and output are of resistive termination so far. But it is not always the case in practice. Owing to the uninterrupted development of electronics, it is increasingly conspicuous to develop the realization theory of transfer function of the network composed of single or/and two-port arbitrary RC terminations. For this reason, an easy-to-use synthesis method as taking some prevailing methods as particular cases is generalized and simplified through mathematical proof. Application of this method is instanced.Summary.1. The N-type function and its criterion theorem are defined and derived as follows. If a rational function N(s) can be decomposed into two terms of a product-- the RC impedance and the RC admittance, it is called as a N-type function. Being a N-type function, the necessary and sufficient conditions are: all the zeros and poles of N (s) are on the negative real axis and, all the pairs of both zero and pole can be paired off infinitely along the negative real axis from origin to left.2. Let N-type function be N(s) = D(s)/F(s) and the relation between the distribution of the zeros of Q(s) and that of the zeros and poles of N (s) is:(1)in the interval (-b10], there is a zero or pole of N (s);(2)in the interval (-bj+1,-bj) where ; = 1,2, ....q0 - 1, the total number of zeros and poles of N (s) is 2;(3) in the interval(-∞, -bq1), the number of zeros and poles and poles of N(s)is not more than 1;(4) at both sides of -bj, there is one zero and one pole of N(s) respectively.3. Thus, a generalized method to solve the open-circuited impedance and short-circuited admittance parameters are given.
