| Abstract: | A design proposal was introduced to digitize the analog shortwave receiver.The design continued to use the original analog shortwave receiver to receive the short-wave signals and export the intermediate frequency signals.The intermediate frequency signals were treated by a serial of digital processes including gain control,analog-to-digital converting,spatial diversity synthesis,signals demodulation,digital-to-analog converting and low pass filtering.These treatments thereby improved the performance of sho... |
