摘要： A technique for determining a tuning frequency of an audio receiver includes interrupting a received radio frequency (RF) signal at an input of the audio receiver. Next, a modulated audio signal is injected into the input of the audio receiver. Then, it is determined whether the demodulated audio signal is present at an output of the audio receiver. If not, the frequency of the modulated audio signal is changed until the demodulated audio signal is detected at the output of the audio receiver.
