Patent ID: 7899135

Claim:
A decoder comprising: at least one radio processor which converts a received radio signal into a digital radio encoded baseband signal; a sample rate converter operably coupled to convert, based on an error feedback signal, rate of the digital radio encoded baseband signal from a first rate to a second rate to produce a digital radio rate adjusted encoded baseband signal; a digital decoder operably coupled to decode the digital radio rate adjusted encoded baseband signal to produce a decoded radio composite signal; a channel separator operably coupled to separate a left channel signal and a right channel signal from the decoded radio composite signal; and an error sensor operably coupled to produce the error feedback signal based on the decoded radio composite signal, wherein the error sensor functions to: determine a period of the decoded radio composite signal based on a known property of the decoded radio composite signal; compare the period of the decoded radio composite signal with an ideal period; and generate the error feedback signal based on a difference between the period of the decoded radio composite signal and the ideal period.
