The transmission matrix $([T])$ of a circuit is defined as follows:

$$
\left[\begin{array}{l}
v_1(r) \\
i_1(t)
\end{array}\right]-\left[\begin{array}{ll}
r_{11} & r_{12} \\
r_{21} & r_{22}
\end{array}\right]\left[\begin{array}{l}
v_2(r) \\
t_2(t)
\end{array}\right]+[T]-\left[\begin{array}{ll}
t_{11} & t_{12} \\
t_{21} & t_{22}
\end{array}\right]
$$


The transmission matrix of the circuit shown in Figure 10.13.2 can be determined as follows:
Applying KVL in the loop:

$$
-v_1(r)+v_2(t)-0 \Rightarrow v_1(t)-v_2(t)
$$


Applying KVL in the right-side mesh:

$$
-v_2(r)+R\left(i_1(t)-i_2(r)\right)-0 \Rightarrow i_1(t)-\frac{1}{R} v_2(t)+i_2(t)
$$


Solving (1), (2), and (3):

$$
\left[\begin{array}{l}
v_1(t) \\
l_1(t)
\end{array}\right]-\left[\begin{array}{ll}
1 & 0 \\
\frac{1}{R} & 1
\end{array}\right]\left[\begin{array}{l}
v_2(t) \\
i_2(t)
\end{array}\right]+\left[T_P\right]-\left[\begin{array}{cc}
1 & 0 \\
\frac{1}{R} & 1
\end{array}\right]
$$


The transmission matrix of the circuit shown in Figure 10.13.3 can be determined as follows:
Applying KVL in the loop:

$$
-v_1(t)+R i_2(t)+v_2(t)-0 \Rightarrow v_1(t)-R i_2(t)+v_2(t)
$$


From the circuit, it is clear that:

$$
i_1(t)-i_2(t)
$$


Solving (1), (5), and (6):

$$
\left[\begin{array}{l}
v_1(r) \\
v_1(t)
\end{array}\right]=\left[\begin{array}{ll}
1 & R \\
0 & 1
\end{array}\right]\left[\begin{array}{l}
v_2(t) \\
t_2(t)
\end{array}\right] \Rightarrow\left\|T_s\right\|=\left[\begin{array}{ll}
1 & R \\
0 & 1
\end{array}\right]
$$


The circuit of Figure 10.13.1 can be assumed like the series connection of seven small circuits. The total transmission matrix of sach a circuit can be determined as follows:

$$
\begin{aligned}
{[T]-\left[T_{p 1}\right] \times\left[T_{s 1}\right] \times\left[T_{p 2}\right] \times\left[T_{s 1}\right] \times\left[T_{p 2}\right] \times\left[T_{s 1}\right] \times\left[T_{p 1}\right] } \\
-\left[\begin{array}{ll}
1 & 0 \\
\frac{1}{1} & 1
\end{array}\right] \times\left[\begin{array}{ll}
1 & 1 \\
0 & 1

CircuitSense

This dataset is a comprehensive multimodal circuit question-answering benchmark designed to evaluate visual reasoning and problem-solving capabilities across three main domains: Perception, Analysis, and Design. The dataset contains structured question-answer pairs with accompanying visual content, targeting different engineering cognitive levels and reasoning tasks.
