PPT-Lab 7: Crystal Radio

Spreadsheet Upload Only Today The Crystal Radio Signal Flow Through the Radio Due to bandwidth limitations of the earpiece it averages over the fast oscillation and gets zero without the diode The amplitude modulating frequency is slow The carrier frequency is fast compared to the response of the earpiece.
