ABSTRACT:
A fidelity measuring apparatus (103). The fidelity measuring apparatus (103) measures the fidelity of a system (101). A preprocessor (109) receives an input signal. The preprocessor (109) also receives an output signal from the system (101). The preprocessor (109) extracts a feature set from the output signal. An artificial intelligence tool (111), trained in the relationship between fidelity and the feature set, generates an output that is a measure of the fidelity of the system (101). A fidelity measuring apparatus (103b) includes a preprocessor (138) and two or more artificial intelligence tools (111-N). The artificial intelligence tools (111-N) are independently trained by input signals from different sources. An averaging circuit (140) averages the output of each artificial intelligence tool (111-N). The fidelity measuring apparatus (103b) operates to produce accurate fidelity measurements independent of the input signal, the source of the input signal and the technology of the system.
