In this video we explore some of the simple mathematics of amplitude modulation, see how sidebands arise, and illustrate these concepts using a digital oscilloscope in FFT mode. Interestingly, research into SSB began in the early 1900s, as described in www.arrl.org/files/file/Technology/pdf/McElroy.pdf. There are numerous resources on the Net with additional information beyond what is presented here; see, e.g., www.radio-electronics.com/info/rf-technology-design/am-amplitude-modulation/theory-equations.php and the several tutorial pages at that URL.
