The BFO is a radio frequency electronic oscillator that generates a constant sine wave at a frequency f BFO that is offset from the intermediate frequency f IF of the receiver. This signal is mixed with the IF before the receiver's second detector ( demodulator ).
BFO is an abbreviation that stands for: Basic Formal Ontology; Beat frequency oscillator used to create an audio frequency signal for receiving continuous wave (Morse code) transmissions; The Black Forest Observatory in Germany; BiFeO 3 (Bismuth ferrite), an inorganic chemical compound; Boron monofluoride monoxide; Budapest Festival Orchestra
