Multipath detector using phase comparison of stereo pilot signal. |
摘要 |
<p>A frequency modulation (FM) stereo broadcast receiver detects the onset of multipath interference based on phase changes in the received stereo pilot signal. In a preferred embodiment, the phase of the received pilot signal is compared to the phase of a regenerated pilot from a phase-locked loop in a stereo decoder circuit (22). The severity of a multipath event is determined by the phase shift detected at the onset of the multipath event. <IMAGE></p> |
