The realization of general hybrid matrices for resistive multiports is a problem which is of particular interest in the time domain synthesis of

networks from the state model. The hybrid matrix

can be partitioned in the form
![H = \\left[ H_{11} & H_{12} \\ H_{21} & H_{22} \\right]](/images/tex/11206.gif)
. Two cases are discussed in this paper: 1) Realization of networks for which

is an

-matrix. 2) Realization of networks for which

is not an

-matrix. In both cases

and

can be singular. Necessary and sufficient conditions for the realization of a given matrix as the hybrid matrix of a resistive

-port network are given for the simple case in which

is an

-matrix. Sufficient conditions are given for the more complicated class of networks for which

is not an

-matrix. A computer program realization technique is presented for both these classes of networks.
