INTRODUCTION

The previous chapter showed that:

1. All the element voltages and element currents in a circuit can be obtained from its node voltages. The node voltages are governed by a matrix equation YV = CU, where V is the node voltage column vector, Y is the nodal conductance matrix of the circuit, U is the input column vector containing source functions of all independent voltage sources and current sources in the circuit and C is the input matrix. The values of conductances in the circuit and values of coefficients of linear dependent sources in the circuit decide the elements of Y-matrix. It is a symmetric matrix if there are no dependent sources in the circuit. Dependent sources can make Y-matrix asymmetric. The C-matrix, in general, contain ...
