Abstract
A correlation meter is disclosed for determining tuning status of a tunable receiver. The correlation meter receives an output of the tunable receiver, such as an acoustic audio output of the tunable receiver. An analog to digital converter converts the output of the tunable receiver to a digital sample side representation. An antenna or other signal collector receives reference side representations corresponding to channels to which the tunable receiver may be tuned. The correlation meter correlates the digital sample side representation and the reference side representations as the reference side representations are received by the correlation meter in order to determine the tuning status of the tunable receiver.
