    摘要: A multi-jack detector for detecting states of a plurality of jacks. Each jack comprises a first switch having a first normally closed terminal and a first output terminal. The multi-jack detector comprises a plurality of bias resistors each coupled to one of the first output terminals, respectively; a control unit for determining the states of the plurality of jacks; wherein the first normally closed terminals are commonly coupled to a first node and the control unit determines the states of the plurality of jacks according to a voltage at the first node. Because the voltage at the first node is different for each state of the jacks, the detector can detects the states of the jacks using a single I/O pin.

    摘要: An audio mixing device and method are provided. The audio mixing device includes an analog to digital converter (ADC), a converting module, a mixing module, and a down-sample filter. The ADC is adapted to receive an analog signal, and convert the analog signal into a first digital signal. The converting module receives the second digital signal, and adjusts a data rate of the second digital signal according to a data rate of the first digital signal to generate a third digital signal. The mixing module mixes the first digital signal and the third digital signal to output a mixed signal. The down-sample filters down-samples the mixed to output a down-sampled signal.
