摘要： 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.

摘要： A testing method or apparatus utilizes a filter or modifier to measure time varying or dynamic harmonic, intermodulation, cross modulation, and or N-Beat or triple distortion from a device. With a stairstep or arbitrary signal and another signal, Nth order harmonic, cross modulation, triple beat, N-Beat, and or intermodulation distortion is measured via the filter or modifier at different offsets or time provided by an arbitrary low frequency signal. For example, an amplifier with crossover distortion will show increased (e.g., time varying) harmonic, cross modulation, triple beat, and or intermodulation distortion near the zero crossing while providing less distortion in other portions of the transfer curve of the amplifier. One or more distortion signals from the device (e.g., audio device) may be measured for a phase and or frequency modulation effect.

摘要： A method and apparatus is disclosed which reduces or removes the effectiveness of commercial skip systems such as presently found in VCRs, PVRs, etc. which are designed to delete commercials from signal material upon playback of a previously recorded version of the signal material. In an embodiment, the effectiveness of the commercial skip system is reduced or removed by adding a flat field of selected signal level to active line portions of video lines of the signal material. Other embodiments modify the normal fade to black signal indicative of a commercial to provide a fade to non-black signal. In further embodiments, a fade to non-black signal is inserted in an overscan area of the signal picture. Still further embodiments modify audio signals or selected signals in the horizontal blanking interval which may be used in commercial skip systems to detect the presence of commercials.

摘要： A testing method or apparatus utilizes multiple frequencies applied to a device under test for measuring newly discovered frequency modulation effects. An embodiment may include a lower frequency signal combined with two (or more) higher frequency signals to test a dynamic change in frequency response, gain, and or phase of the lower frequency signal from an audio device. This dynamic test can reveal frequency modulation effects via the two higher frequency signals emulate a modulated signal that provides a phase or frequency modulation frequency related to the difference of the two higher frequency signals. Another embodiment may include the use of a higher frequency signal and pulsed waveform to dynamically induce a time varying phase or frequency distortion of the pulsed waveform or components of the pulsed waveform from the device that has differential phase distortion. In another embodiment, the device's output is then measured with an FM detector and or phase detector to measure a phase and or frequency shift in one or more signals of the frequencies related to the pulsed waveform, such as a signal of the fundamental frequency and or one or more harmonic related to the pulsed waveform the device.

摘要： A testing method or apparatus utilizes multiple frequencies applied to a device under test for measuring newly discovered frequency modulation effects. An embodiment may include a lower frequency signal with a smaller amplitude higher frequency signal to test a dynamic change in frequency response, gain, and or phase. This dynamic test can reveal frequency modulation effects. Another embodiment may include the use of a multiple frequency signal or a modulated signal such as an amplitude modulated to dynamically induce a time varying phase or frequency distortion for the device that has differential phase distortion. In another embodiment, the device's output is then measured with an FM detector, Wow and/or Flutter meter, phase detector, and or spectrum analysis system to measure a shift in one of the frequencies used in the test signal or to measure phase and or frequency modulation effects of any signals such as a distortion product, a carrier signal, and or a distortion product of the carrier signal from the device.
