State-space analysis of lumped/distributed networks in time and frequency domains

Lumped/distributed networks are analysed using state-space techniques. The state and output equations are derived using topological methods with no restrictions on the topology. The method is applied to noncommensurate circuits and to coupled transmission-line circuits in inhomogeneous media. Computer programs have been developed for the analysis of these circuits in both the frequency and time domains. The time response, for any set of inputs, is obtained without the need of either the explicit form of the transfer function or the use of convolution.
