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 1):
A method for measuring a phase modulation, amplitude modulation, or frequency modulation effect of a cross modulation distortion signal from an audio device, wherein the audio device has an input and an output, comprising:\n providing at least two signals comprising at least a first signal, and a second signal comprising a frequency modulation signal whose carrier frequency is higher than the frequency of the first signal to an input of the audio device and whose frequency modulating frequency is less than the frequency of the first signal; coupling an output signal of the audio device to an input of a modifier, and wherein the modifier provides an output terminal; measuring the cross modulation distortion signal from the output terminal of the audio device with a first phase modulation demodulator, first amplitude modulation demodulator, or a first frequency modulation demodulator, and wherein the cross-modulation distortion signal is related to the first signal.
