Digital Frequency Modulation Also Known as Frequency-Shift Keying (FSK)
Digital frequency modulation, also referred to as Frequency-Shift Keying (FSK), with binary FSK denoted as 2FSK. This digital modulation technique uses the frequency of a carrier wave to transmit digital messages by controlling the carrier's frequency based on the input data. In 2FSK signals, the symbol "1" corresponds to one carrier frequency, while the symbol "0" corresponds to a different carrier frequency, with instantaneous switching between frequencies. Implementation often involves generating two distinct sinusoidal waveforms and switching between them using digital logic or lookup tables in code.
