  • Active noise cancellation system for headphone
    Patent number: 10609468
    Abstract: An active noise cancellation system comprising an active noise cancellation circuit connected to a microphone arranged to sense environmental noise, the active noise cancellation circuit comprising: —an analog-to-digital converter (ADC) arranged to convert the sensed environmental noise to a digital environmental noise signal, —a prediction filter configured for predicting a plurality D of inverted digital environmental noise samples and generating a digital inverted environmental noise signal, —a digital-to-analog converter (DAC) to convert the digital inverted environmental noise signal to an analog inverted environmental noise signal for cancelling the environmental noise.
