rfckt.rlcgline class - Package: rfckt

RLCG transmission line

Syntax

h = rfckt.rlcgline h = rfckt.rlcgline('Property1',value1,'Property2',value2,...)

Description

Use the rlcgline class to represent RLCG transmission lines that are characterized by line loss, line length, stub type, and termination.

h = rfckt.rlcgline returns an RLCG transmission line object whose properties are set to their default values.

h = rfckt.rlcgline('Property1',value1,'Property2',value2,...) returns an RLCG transmission line object, h, with the specified properties. Properties that you do not specify retain their default values.
