Abstract:
1. A method for blending a radio signal comprising: receiving, with a receiver, a hybrid radio signal that includes an analog radio signal and a digital radio signal; determining, with the receiver, absence of the digital radio signal from the hybrid radio signal; determining, with the receiver, presence of the digital radio signal in the hybrid radio signal subsequent to the determining absence of the digital radio signal from the hybrid radio signal; determining, with the receiver, an audio correlation between the analog radio signal and the digital radio signal in response to the determining presence of the digital radio signal in the hybrid radio signal and in response to a signal blend count parameter being greater than or equal to a determined signal blend parameter; blending, with the receiver, from the analog radio signal to the digital radio signal in response to the determining presence of the digital radio signal in the hybrid radio signal and in response to the audio correlation being greater than a predetermined audio correlation threshold or the signal blend count parameter being less than or equal to the determined signal blend parameter; and processing, with the receiver, the digital radio signal in response to the determining presence of the digital radio signal in the hybrid radio signal.
