T-section

A network is said to be T-section when it looks like a T. The asymmetrical and symmetrical T-sections are shown in Figure 1 (a) and Figure 2 (b), respectively.

In an asymmetrical T-section, the total series impedance is Z₁ + Z₃ whereas in symmetrical T-section the total series impedance is 2Z₁. The shunt impedance in both the cases is Z₂.

Figure 2 (a) and Figure 2 (b) show the unbalanced and balanced T-section, respectively of symmetrical configuration. The unbalanced and balanced asymmetrical configurations can also be shown in the same way. The balanced T-section is also called as H-section.
