It's like a Crystal Radio that was a direct sampling device that go's almost to radios pre-history . It was used for AM radio . It was just a L/C circuit that tuned in a radio station and ran the RF a crossed a diode turning the RF to audio that went to ear phones . Direct sampling is were the RF with out any processing goes to the A/D converter.
