Audio processing apparatus and method having noise reducing mechanism - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240339970 titled 'Audio processing apparatus and method having noise reducing mechanism
Simplified Explanation: The patent application describes an audio processing apparatus with a noise-reducing mechanism. It involves generating a digital audio signal, performing modulation processing to generate a single-bit waveform modulated signal, and converting it to an analog signal for output.
- The apparatus includes a DSP circuit that generates an n-bit digital audio signal.
- A first modulation circuit truncates the digital audio signal and performs modulation processing to generate a single-bit waveform modulated signal.
- An amplifier includes a single-bit DAC circuit, a second modulation circuit, and a driving circuit.
- The single-bit DAC circuit converts the single-bit waveform modulated signal to generate an input analog signal.
- The second modulation circuit subtracts the input analog signal and an output modulated signal to generate a subtraction result and a control signal.
- The driving circuit generates the output modulation signal according to the control signal and transmits it through a closed-loop feedback path.
