What is 2FSK?
2FSK (Binary Frequency Shift Keying) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier signal.
Unlike more complex modulation schemes, 2FSK uses just two frequencies to represent binary data - typically one frequency for binary "1" and another for binary "0".
This modulation technique is widely used in various applications including:
- Low-power IoT devices
- Digital mobile radio
- Wireless sensors
- Amateur radio communications
