INTRODUCTION�

  • One port network: Any active or passive network having only two terminals can be represented by an one port network.
  • Two port network: A network having two pairs of terminals can be represented by a two port network, where one pair of terminals designated as input and the other being output.
  • n – port network: If the network representation contains n number of pair of terminals, it is called a n port network.

NETWORK CONFIGURATION

T – section:

  • In a symmetrical T – section, the series arm impedance is equal in both the sides of the shunt arm impedance.
  • In unsymmetrical T – section, the series arm impedance is unequal in both the sides of the shunt arm impedance.
  • Balanced symmetrical T – section
  • Unbalanced symmetrical T - section
