Analysis of initial approximation structure and trajectories of design of analog networks

A. M. Zemliak


Various trajectories of design, arising from the new methodology of analog network design, are analyzed. Several major criteria suggested for optimal selection of initial approximation to the design process permit to minimize the machine time. The initial approximation point is selected with regard to the previously revealed effect of acceleration of design process. The concept of separatrix is defined making it possible to determine the optimal position of the initial approximation. The numerical results obtained for passive and active networks prove the possibility of optimal choice of the initial point in design process.
