Patent ID: 8260943

Claim:
A signal modeling apparatus for analyzing operation of a transmitting device comprising: an input coupled to receive a captured real-time signal of a real-time signal outputted by said transmitting device; a signal modification module that applies a transmitter compliant transfer function, wherein includes specifications describing both transmitter characteristics of the transmitting device and signal quality at a receiver, to said captured real-time signal to create a modified signal, said transmitter compliant transfer function being a transfer function defined by at least one protocol specification that characterizes modifications to a signal that passes through a communications medium that complies with said at least one protocol specification, said modified signal being a model of said real-time signal as received at the receiver device after passing through said communications medium that complies with said at least one protocol specification, said signal modification module being implemented in computer readable instruction code operating on a device capable of running said computer readable instruction code; and an output coupled to transmit said modified signal to a display device in order to permit analysis of said transmitting device operation relative to said at least one protocol specification.
