When you think of advancements in signal modulation, your mental time machine might go back to the turn of the 21st century and LTE which was proposed by NTT DOCOMO as “Super 3G” in early 2004. But over a hundred years earlier, on June 3rd, 1900, in the city of São Paulo, Brazil, the Reverend Father Roberto Landell de Moura demonstrated the transmission of voice messages over a distance of 8 km using amplitude modulation. Several months later, on December 23, 1900, Reginald Aubrey Fessenden successfully transmitted an amplitude-modulated signal approximately 1.6 km. Throughout the nearly 123 years since these transmissions occurred, arguably no modulation scheme has been of greater significance in world history than amplitude modulation (AM).
