==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.
