    Abstract: Improved methods and systems that assist a user in searching media items on a portable electronic device are disclosed. According to one aspect of the invention, a portable electronic device is provided with a search function that enables a user to search for media items resident on the portable electronic device. The search function can search through different types of media items. Those of the media items that are deemed matching can be ranked in order of relevance and displayed in a list for the user. Thereafter, the user can navigate the list to select one of the listed media items for playback. According to another aspect of the invention, various graphical user interfaces can be presented on a portable electronic device to assist a user in interacting with the portable electronic device to utilize a search function.

    Abstract: An device and method for a pre-sampling processing is disclosed. The pre- sampling device includes a single amplifier having a virtual ground node, and a feed back circuit connected from an output of the amplifier to the virtual ground node. The feed back circuit includes a plurality of switches connected to the virtual ground node. The switches control a plurality of programmable gain settings. The feed back circuit also includes an adjustable current source that is adjusted according to an estimated echo signal. A current of the adjustable current source is summed at the virtual ground node. The feed back circuit also includes a low pass filter that is tuned to suppress received signal frequencies above a fraction of a sampling frequency of a sampler connected to the pre-sampling device.

    Abstract: An ADC system includes a plurality of N/2 sub-ADCs (220-224), each sub-ADC receives an analog signal (ANALOG) and a clock signal and generates two digital sampples at a rate of Fs/N (clock VsIH). The two digital samples are genererated with approximatel 180 degree phase relationship relative to a frequency of Fs/N. The plurality of N/2 sub-ADCs of the time interleaved ADC system generates a combined output samples at a rate of Fs.
