An RFID chip is modified with set data before being disposed in an electronic label so as to allow the electronic label to be selectively used with different types of RFID systems. The RFID chip includes a first data storage zone for storing first data set accessible by the first type of RFID system and the second type of RFID system; and a second data storage zone for storing second data set inaccessible by the first type of RFID system and the second type of RFID system. The second data set includes a modifiable code for indicating a type of the electronic label and with which of the first type of RFID system and the second type of RFID system the electronic label is to be used.

An audio processing circuit includes a clock synthesizer, a clock divider, a digital interpolator module, a sampling rate converter and a digital-to-analog converter. The clock synthesizer generates a base clock signal according to a sampling clock signal and a first reference clock signal. The clock divider generates a multiple frequency clock signal according to the base clock signal. The digital interpolator module interpolates a digital audio data according to the multiple frequency clock signal. The sampling rate converter processes the interpolated digital audio data into a re-sampled digital audio data according to the multiple frequency clock signal and a second reference clock signal. The digital-to-analog converter is coupled to the sampling rate converter for converting the re-sampled digital audio data into an analog audio signal according to the second reference clock signal.
