Abstract
A system and a method are provided for detecting a type of a received signal. The system includes a processor (32) and two receivers (24, 26). Both receivers (24, 26) are coupled to the processor (32). The first receiver (26) is capable of receiving a first signal type, and the second receiver (24) is capable of receiving a second signal type. An algorithm (30), coupled to the second receiver (24), is used for distinguishing between the first signal type and the second signal type. The algorithm (30) is used after the first receiver (26) begins storing the signal as a first signal type, and after the second receiver (24) begins storing the signal as a second signal type. At least one of the two signal types is retained.
