摘要： An electronic circuit includes an analog to digital converter (ADC) and a noise coupling filter. The ADC generates a digital output signal based on a first analog signal and a second analog signal. The noise coupling filter generates the second analog signal to be fed back for an input to the ADC, based on a first quantization error signal associated with converting the first analog signal to the digital output signal. The noise coupling filter performs noise shaping on a digital error signal derived from the quantization error signal and generates the second analog signal from a result of the noise shaping, using a clock in the digital domain.

摘要： An example method, performed by an edge data network, of providing a web service to a terminal includes: receiving, from the terminal, a request for access to a web page; identifying uniform resource locators (URLs) of a plurality of pieces of content for displaying the web page, the URLs being included in a hypertext markup language (HTML) of the web page; identifying first content cached by the edge data network from among the plurality of pieces of content for displaying the web page; changing a URL of the first content among the URLs of the plurality of pieces of content to a URL representing a location at which the first content is cached to modulate the HTML; and transmitting the modulated HTML including the changed URL of the first content to the terminal.

摘要： An audio device includes a channel detection electrode and a jack detector configured to determine whether the channel detection electrode is in contact with a jack according to voltage variation of a detection node. The jack detector includes a first resistor coupled between the detection node and a first node to which a first voltage is supplied, a second resistor coupled between the detection node and the channel detection electrode, a third resistor coupled between the detection node and a second node, and a comparator configured to compare a voltage at the detection node with a reference voltage.

摘要： An audio jack detection circuit includes an impedance detecting circuit configured to generate a detection signal corresponding to an impedance between a ground pin and a ground detection pin, which are in contact with a ground terminal of an audio jack socket, and a controller configured to determine a state of the audio jack socket based on the detection signal. A detection range of the impedance detected by the impedance detector may be controlled by varying a resistance of a pull-up resistor connected to the ground detection pin.
