Photon heterodyning
A heterodyne is a signal frequency that is created by combining or mixing two other frequencies using a signal processing technique called heterodyning, which was invented by Canadian inventor-engineer Reginald Fessenden. Heterodyning is used to shift signals from one frequency range into another, and is also … See more In 1901, Reginald Fessenden demonstrated a direct-conversion heterodyne receiver or beat receiver as a method of making continuous wave radiotelegraphy signals audible. Fessenden's receiver did not see much application … See more Heterodyning, also called frequency conversion, is used very widely in communications engineering to generate new frequencies and … See more • Electroencephalography • Homodyne • Transverter • Intermodulation – a problem with strong higher-order terms produced in some non-linear mixers See more Heterodyning is based on the trigonometric identity: The product on the … See more • Hogan, John V.
