  • Patent number: 7728660
    Abstract: An audio signal processing system and method is disclosed. In a particular embodiment, the audio signal processing system includes a first electrical path responsive to a power supply of an audio amplifier. The first electrical path can include a low pass filter to filter a direct current (DC) component of the power supply and a first analog-to-digital converter (ADC) responsive to the low pass filter. The audio signal processing system also includes a second electrical path responsive to the power supply. The second electrical path can include a high pass filter to filter an alternating current (AC) component of the power supply and a second ADC responsive to an output of the high pass filter. The audio signal processing system includes compensation logic to modify an audio signal based on a first signal generated from the first electrical path and a second signal generated from the second electrical path.

  • Publication number: 20060034365
    Abstract: A digital timing read back and an adaptive feedforward compensation algorithm to reduce harmonic distortion is disclosed. More specifically, the approach generates harmonic components digitally with the same magnitude but at an opposite phase to the output harmonic distortion. An anti-distortion signal is generated and added to the input signal. The magnitude and phase of the harmonic distortion change with the modulation level or index and the frequency of the input signal. In addition, the harmonic distortion level varies significantly with different timing error statistics in different power devices. The inventive method takes the modulation level or index, the frequency of the input signal and the timing error statistics acquired through a digital read back circuit as input variables to determine the magnitude and phase of the anti-distortion signal.
