Abstract:
A system is provided to analyze cross-modulation distortion in audio devices, which may include testing with audio frequencies. One or more distortion signals from the audio device may be measured for an amplitude, phase, and or frequency modulation effect. In another embodiment a musical signal may be used as a test signal. Providing additional test signals to the audio device can induce a time varying cross-modulation distortion signal from an output of the audio device. Also utilizing at least one additional filter, filter bank, demodulator and or frequency converter and or frequency multiplier provides extra examination of distortion.

Claim (Index 13):
A method for measuring a phase modulation or frequency modulation effect from an audio device, wherein the audio device has an input terminal and an output terminal, comprising:\n providing at least two signals comprising at least a first signal, and a second signal whose frequency is higher than the fundamental frequency of the first signal, to the input terminal of the audio device; coupling the output terminal of the audio device to an input of a modifier or first filter, and wherein the modifier or first filter provides an output terminal; further coupling the output terminal of the modifier or first filter to an input terminal of a frequency multiplier circuit or function and coupling an output terminal from the frequency multiplier circuit or function to an input terminal of a phase modulation demodulator and or frequency modulation demodulator, wherein the phase modulation demodulator and or frequency modulation demodulator includes an output terminal; measuring the phase or frequency modulation distortion signal of the audio device via the output terminal of the phase modulation demodulator or a frequency modulation demodulator.
