Not Exported

• SParameters{NUMPORTS, DATATYPE}: Stores S parameters.
• ZParameters{NUMPORTS, DATATYPE}: Stores Z parameters.
• YParameters{NUMPORTS, DATATYPE}: Stores Y parameters.
• HParameters{DATATYPE}: Stores H parameters.

Function Listing

Constructors

• Network({::Symbol/::NPType}, nwkpar::Array[, z0=[::Real]]): Constructs concrete network parameter matrix <: Network.
• Network(:S, [0 1; 1 0], z0=50): Construct S parameter network (z0=50 Ω).
• Network(NPType{:S}, [0 1; 1 0], z0=50): Construct S parameter network (z0=50 Ω).
• ...

Traits (Utility functions for instances and types)

• Symbol(::NPType): Returns symbol value corresponding to an NPType.
• eltype(::NetworkParameters): Returns a network parameter matrix element type.
• portcount(::NetworkParameters): Returns the port count.

Conversion Routines

• Network({::Symbol/::NPType}, nwkpar::NetworkParameters[, z0=[::Real]]): Performs network parameter matrix conversion.
• Network(:S, Z, z0=50): Convert Z ⇒ S parameter network (z0=50 Ω).
• Network(NPType{:S}, Z, z0=50): Convert Z ⇒ S parameter network (z0=50 Ω).
• vector_push(np::Vector{NetworkParameters}): Converts Vector{NetworkParameters{Number}} ⇒ NetworkParameters{Vector{Number}}
• vector_pull(np::NetworkParameters{Vector}): Converts NetworkParameters{Vector{Number}} ⇒ Vector{NetworkParameters{Number}}
• submatrix(np::{S/Y/Z}Parameters, ports::Vector{Int}): Creates a network parameter matrix that is a subset of np. Can also be used to re-order ports.

Other

• series({::Symbol/::NPType}, {::TImpedance/::TAdmittance}): Returns a 2-port network parameter matrix representing the provided series impedance/admittance value.
• shunt({::Symbol/::NPType}, {::TImpedance/::TAdmittance}): Returns a 2-port network parameter matrix representing the provided shunt impedance/admittance value.
