two-port network transmission parameters?? 1. The problem statement, all variables and given/known data 2. Relevant equations t[A B]=[t11 t12] [C D]=[t21 t22] 3. The attempt at a solution so, first thing i did was find the equivalent capacitance/inductance. C(eq)=-j0.5 and L(eq)=j0.5. using these values as I was confused by parametric equations in general i decided to do nodal equations. using V1 as the node left of resistance R, V2 as the one right of it. since in my book, they do nodal equations to check the values of y-paramter matrices. V1 equation: (1+j2)V1+(-1)V2=0 V2 equation: (-1)V1+(1-j2)V2=0 since the t equation (choice A) had different sign values than the nodal matrix, i guessed this was wrong. choice B also looked wrong because it only had the C(eq) value, so I chose choice D because that looked similar to (1-j2)V2 in the equation for V2. i obviously know i am doing this wrong. EDIT: looking over my notes i think this is a 't-parameter' problem. According to my teacher, the T-parameter matrices for each of the following: Z(ohm) [T] matrix: Code (Text): [1 z] [0 1] Y(s) [T] matrix: Code (Text): [1 0] [Y 1] where Z and Y are the values. i am assuming Z if for resistor or any real value, Y is for imaginary part and I think the admittance. i still don't know why the matrices are structured like this, though. but if i assume this is correct, choices B, C, and D are all wrong because they don't follow the format. that leaves only A.
