There is provided an audio data processing device. The device includes an IN terminal to which first audio data from outside are input, a THRU terminal from which the first audio data are output to the outside, an FPGA which signal-processes the first audio data from the IN terminal, an OUT terminal from which second audio data which are signal-processed are output to the outside, and a power supply switch. The FPGA outputs the first audio data from the IN terminal to the THRU terminal without any processing when the power supply switch is in an ON state and is also supplied with operational power and outputs the first audio data from the IN terminal to the THRU terminal without any processing when the power supply switch is in an OFF state.

摘要:
A battery tester determines a remaining level of charge of a battery mounted within a separate electronic device having an audio jack. The battery tester includes a plug and a circuit having a high impedance input amplifier. At least one electrical contact of the plug is electrically coupled to an input of the high impedance input amplifier. The plug is removably insertable within the audio jack such that the battery of the separate electronic device is electrically connected to the input of the high impedance input amplifier. When electrically coupled to the battery, an output of the high impedance input amplifier provides a signal proportional to the remaining level of charge of the battery, whereby the remaining level of charge of the battery is obtainable by the battery tester without having to remove the battery from the electronic device.
