摘要： An Audio Codec which comprises a power selecting circuit an audio compiler circuit and a control amplifier circuit. The power selecting circuit receives at least a primary power source and an auxiliary power source and outputs a working power selected from the power sources. The auxiliary power source is selected and output to the control amplifier circuit only when the computer is at a power-off status. When the computer is power-on, the primary power source will be selected and output to both the audio compiler circuit and the control amplifier circuit. Therefore, the Audio Codec of the present invention only needs one set of internally furnished control amplifier circuit to both operate on the normal power-on status and perform the Power OFF CD function.

摘要： The present invention offers an over-sampling digital-to-analog converter with variable sampling frequencies to process input signals of variable sampling frequencies. The over-sampling digital-to-analog converter comprises an expander, which expands said input signals with a fixed rate of M to produce over-sampling signals; a digital low-pass filter, which filters out high-frequency ingredients of over-sampling signals and then outputs data with a first rate; a data buffer, which receives the outputted data by said digital low-pass filter with the first rate and outputs the data with a second rate; a modulator, which reads data in said data buffer with the second rate and modulates the data; a digital-to-analog converter, which converts the modulated data to analog signals; and an analog low-pass filter, which filters out high-frequency ingredients of said analog signals for producing output signals. No matter how the sampling frequency of the input signals is, due to reading rates of the modulator are the same, the over-sampling digital-to-analog converter ensures that noise is mostly distributed in the high-frequency band.

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.
