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 quality 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, at the battery-powered handheld audio device, an indicia of signal quality for a received continuous-time radio signal; comparing the indicia of signal quality to a signal quality threshold; upon a favorable comparison, enacting a first analog signal conditioning setting for conditioning a signal corresponding to the continuous time radio signal; and upon an unfavorable comparison, enacting a second analog signal conditioning setting for conditioning the signal corresponding to the continuous time radio signal;wherein:
the first analog signal conditioning setting includes a first analog filter setting; and the second analog signal conditioning setting includes a second analog filter setting, wherein the first analog filter setting causes a corresponding analog filter to consume less power than the second analog filter setting.
