摘要： A method and system for operating an electronic device (102) that is operably coupled to an audio output device (104) is provided. The method includes receiving an encoded audio file at the electronic device. Further, the method includes selectively decoding (202) the encoded audio file, in correspondence with a spectral response of the audio output device, to provide decoded audio data. Furthermore, the method includes playing (204) the decoded audio data over the audio output device.

摘要： A multi-protocol phone call routing system (10) and method (40) can include a wireless transceiver (22) capable of operating on a primary wireless network (24) and at least one alternative wireless network (32), and a processor coupled to the wireless transceiver. The transceiver can be programmed to monitor (44 or 52) signal quality, location or cost on the primary wireless network or on the alternative wireless network and request (48) to carry traffic on the primary wireless network or the alternative wireless network. The system can be further programmed to request (54) canceling forwarded calls to the alternative wireless network transceiver portion when the signal quality on the primary wireless network reaches above the predetermined threshold and to transfer calls back to the primary wireless network when the signal quality on the primary wireless network reaches above the predetermined threshold and optionally power down (56) the alternative wireless network transceiver.

摘要： A sigma-delta DAC circuit 10 includes a sigma-delta modulator 12 for producing and outputting an n-bit digital signal representative of an input analog signal, wherein n is a positive integer greater than 1, and is preferably equal to 4, 5 or 6. A differential n-bit DAC 30 is for converting a 2n−1-bit digital signal and a 2n−1-bit inverted digital signal processed and output by a bit shifter 24 and a differential decoder 18 to a differential analog signal. The sigma-delta modulator has a movable zero for enabling dynamic spectral shaping of the differential analog signal.
