A sigma-delta DAC circuit includes a sigma-delta modulator 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 is for converting a 2 -bit digital signal and a 2 -bit inverted digital signal processed and output by a bit shifter and a differential decoder to a differential analog signal. The sigma-delta modulator has a movable zero for enabling dynamic spectral shaping of the differential analog signal.

A device for verifying hardware in a circuit arrangement that includes one or more configuration elements () operable to configure hardware elements () that are electrically coupled by one or more electrically-conductive pathways (). The device includes a hardware-verification register () coupled to at least one of the electrically-conductive pathways (). The register () is operable to sample a voltage level on at least one of the electrically-conductive pathways () at a first time point; store in a memory one or more bits, each bit representing the voltage level on at least one of the electrically-conductive pathways () at the first time point; sample a voltage level on at least one of the electrically-conductive pathways () at a second time point; and compare, for at least one of the electrically-conductive pathways, the voltage level at the first time point and the voltage level at the second time point.

A method and system for operating an electronic device () that is operably coupled to an audio output device () is provided. The method includes receiving an encoded audio file at the electronic device. Further, the method includes selectively decoding () 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 () the decoded audio data over the audio output device.

A multi-protocol phone call routing system () and method () can include a wireless transceiver () capable of operating on a primary wireless network () and at least one alternative wireless network (), and a processor coupled to the wireless transceiver. The transceiver can be programmed to monitor (or ) signal quality, location or cost on the primary wireless network or on the alternative wireless network and request () to carry traffic on the primary wireless network or the alternative wireless network. The system can be further programmed to request () 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 () the alternative wireless network transceiver.
