Abstract
A method and apparatus to simulate a length of telecommunications line. One or more bi-directional constant input impedance low pass or pole/zero filters are coupled in series with an attenuator to simulate a length of telecommunications line. The one or more filters are used to approximate the transfer function of the length of telecommunications line.
Claims29
A method comprising:
- providing one or more bi-directional constant input impedance filters;
- and
- simulating a length of telecommunications line using the one or more filters.
An apparatus comprising:
- a telecommunications line simulator having bi-directional constant input impedance.
An apparatus comprising:
- a plurality of electric components;
- and
- means for simulating a behavior of a length of telecommunications line using the plurality of electric components in a ratio of less than five electric components for every 50 feet of the telecommunications line being simulated.
A method comprising:
- providing a length of telecommunications line to be simulated;
- and
- designing a bi-directional constant input impedance line simulator to simulate a behavior of the length of telecommunications line.
