Abstract
Symbolic analysis using direct matrix and interpolationformula methods are discussed. The techniques accommodate passive networks and active networks containing general frequency-dependent devices, themselves represented by rational-function matrices. Subsequently, this leads to the development of partitioned analysis. The suppression of numeric common factors and the determination of the order of complexity of the network are synonymous problems, and simple algorithmic solutions emerge. Simple rules for the choice of sample points leading to accurate analysis are given. Implementation yields a very fast computer-analysis method capable of accuracies comparable with other current techniques.
