METHOD AND SYSTEM FOR ADJUSTING THE DYNAMIC RANGE OF A DIGITAL-TO-ANALOG CONVERTER IN A WIRELESS COMMUNICATIONS DEVICE

摘要

A wireless communication device (100) may include a receiver (110), a memory (104), a digital-to-analog converter (128) an audio playback system (124) and other features. A dynamic range controller (130) selectively generates control signals to adjust, at least in part, the operational dynamic range of the digital to analog converter (128) for digital signals received by the receiver (110) or stored in the memory (104). The selection of dynamic range is based on identifying a characteristic. In one embodiment, the control signals are used to selectively operate the digital-to analog converter (128) at a particular dynamic range based on a sampling rate of a received digital audio signal.
