Power management for a battery-powered handheld audio device

摘要

A method for managing power of a battery powered handheld audio device by receiving an indicia of signal quality for a received continuous-time radio signal. The method compares the indicia of signal quality to a signal threshold. Upon a favorable comparison, enacting a first analog signal conditioning setting. Upon an unfavorable comparison, enacting a second analog signal conditioning setting. The method further provides, upon the favorable comparison, disabling a digital filtering operation, and upon the unfavorable comparison, enabling the digital filtering operation.

1. A method for managing power of a battery-powered handheld audio device, comprises:
receiving an indicia of remaining battery charge of a battery supply; comparing the indicia of remaining battery charge to a battery charge threshold; upon an unfavorable comparison, enacting a first analog signal conditioning setting that includes analog filtering; and upon a favorable comparison, enacting a second analog signal conditioning setting that includes a differing analog filtering, wherein the first analog signal conditioning setting causes less power to be consumed during operation than the second analog signal conditioning setting.
