More Information
Summary:A dual mode mobile handset provides a single set of RF circuit elements which interface with a single set of analog circuit elements thereby reducing redundancy in the system. A DSP connected to the analog circuit elements modulates and demodulates both modes of transmission signals with software elements and pre and post processes the standard signals employing embedded softward. A single control CPU provides data to and receives data from the DSP for selected processing as the first standard transmission signal or the second standard transmission signal.
