Experiment 22 - Software Defined Radio
PrintOverview
In this experiment you will use the Emona DATEx to set up a bandwidth limited signal then use it to explore the difference in the spectral composition of a sampled signal produced using a variety of sampling frequencies above and below the Nyquist Sample Rate. You’ll then use undersampling to demodulate the bandwidth limited signal and recover the message. Finally, you’ll explore the effects on the recovered message of mismatches between the modulated carrier’s bandwidth and the frequency used for undersampling.
