Abstract
An apparatus includes a receiving circuit, a demodulation module, a frame synchronization control module, a filter, and an audio conversion device. The receiving circuit is used to receive a radio frequency signal and generate a corresponding baseband signal. The demodulation module is electrically connected to the receiving circuit for demodulating the baseband signal and for correspondingly outputting sequential data. The frame synchronization control module is electrically connected to the demodulation module for synchronizing the data and outputs the sequential data. The filter is electrically connected to the frame synchronization control module for filtering out erroneous data outputted from the frame synchronization control module. The audio conversion device is connected to the filter for transferring an output of the filter into a corresponding audio signal.
