Hello everyone! I just finished my third exam and I know I won't get a good grade so I'd like to know how to correctly solve this problem: I'm asked to find the T parameters of the circuit shown in the attachment. 1. I know that A is in parallel and I already did that part; well, I have the Z parameters and I was thinking about finding the Z parameters of B as well because A and B are in series so I could just add them up and then transform it into T parameters ¿is this a good approach or what would you recommend? 2. How should analyze the B part of the circuit? some friends said that there are 3 two-ports in series but I can't seem to figure it out. Anyy help will be very much appreciated. Thanks in advance! |

Anyone, please? I just need ideas, not actual math. Thanks in advance! |

I think you need to do the T of both, then multiply them together. I forget the rules for Z, but if adding works then yeah, that too. ;D I don't get the crossover in B, it's just there to confuse... just use whatever (matrix or wye-delta?) reduction you want to solve that with. Tim |

I've already solved and I'm going to post the photos next week. Thank you very much! |

And what do you get if you transform to T parameters? You can't get the overall Z parameters by adding the Z parameters for the A and B parts separately. |
