<p>A method of determining signal quality in a cable network comprises the steps of:
€¢ providing a network model (1) comprising an interconnection model (2) and component models (3),
€¢ providing an input signal (IS),
€¢ determining an output signal (OS) using the input signal and the network model, and
€¢ determining the signal quality from the input signal (IS) and the output signal (OS).
The input signal (IS) comprises multiple constituent signal components, each signal component representing a class of input signals. The step of determining the output signal involves determining intermodulations of the constituent signal components.</p> |
