    Hi everyone,
    i am researcher on network and transmission systems and i have an electrical part to work on it, so i need your help.
    i have a two port network, It is a combination of TL and shunt. To obtain the overall channel response, i multiply the ABCD matrix of the transmission line pieces and the shunts together.
    In our case, the source and destination nodes are connected by a powerline cable which has many branches, so i have to multiply all sectional ABCD
    matrices together sequentially to find the final transfer function. the problem is that i have NAN answer when raising the resulting matrix to the power of the branch density (10,20,30,...).can you please help me to find the mistake, it would be appreciated.
