Chapter 5
Ladder Network
This chapter describes ladder network analysis - a circuit reduction method by which branches of the circuit are
treated as sides (series connection) or rungs (parallel or shunt connection) of a ladder.
5.1 Elements of a Ladder Network
In the examples that follow, the left end of the ladder is the input end and the right end of the ladder is the output
end, where the load is connected. The elements of the ladder (from 1 to N) are entered from right to left, going
from output to input. The input impedance
Zin_
is calculated as if you were “looking in” to the left end of the
ladder.
Field Descriptions - Input Screen
Frequency
: (Frequency) Enter a real number, or algebraic expression of defined terms.
Load_
: (Initial Load) Enter a real or complex number, variable name, or algebraic expression of defined terms.
1:
(Element 1 - closest to the load or output)
...
N:
(Element N - furthest from the load or output)
Field Descriptions - Element Screen
Sixteen different element types are available to build the ladder network. These elements can be inserted in series
or parallel configuration.
Resistor
A resistor can be added as a rung (parallel) or side (series). Choose
Series or Parallel for
