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 7):
A method for measuring a phase modulation, amplitude, or frequency modulation effect from an audio device, wherein the audio device has an input and an output, comprising:\n providing a test signal to an input of the audio device, wherein the audio device includes an output signal; coupling the output signal of the audio device to an input of a modifier or first filter, and wherein the modifier or first filter provides an output terminal; coupling the output terminal of the modifier or first filter to an input of a first amplitude modulation demodulator, phase modulation demodulator, and or frequency modulation demodulator, wherein the amplitude modulation demodulator, phase modulation demodulator, and or frequency modulation demodulator includes an output terminal; measuring amplitude, phase, and or frequency modulation distortion signal from the output terminal of the audio device via the output terminal of the first amplitude modulation demodulator, phase modulation demodulator and or a frequency modulation demodulator; and further coupling to the output terminal of the first amplitude modulation demodulator, phase modulation demodulator and or a frequency modulation demodulator to one or more inputs of a second filter, third filter, and or filter bank, wherein the second filter, third filter, and or filter bank include one or more output terminals; further coupling at least one output terminal of the second filter, third filter, and or filter bank to an input of a second and or third amplitude modulation demodulator, phase modulation demodulator, and or frequency modulation demodulator; wherein the second and or third amplitude modulation demodulator, phase modulation demodulator, and or frequency modulation demodulator include one or more output terminals that provide measurement of static or time varying amplitude, phase, or frequency modulation distortion via signals from the output of the second filter, third filter, and or filter bank.
