rfckt.delay class - Package: rfckt

Delay line

Syntax

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

Description

Use the delay class to represent delay lines that are characterized by line loss and time delay.

h = rfckt.delay returns a delay line object whose properties are set to their default values.

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

Properties
