Abstract
A receiver contains a demodulator system that can derive an analog audio signal and compressed digital data from radio frequency signal. The receiver also contains a decompressor that can decompress the compressed digital data into uncompressed form. A digital to analog converter is used to convert the uncompressed digital data into another analog signal. Control logic is used to allow a user to select either the demodulated analog audio signal or the converted analog signal. The selected signal is delivered to an output device, such as a loudspeaker.
