WebAug 24, 2024 · Therefore, the binary frequency shift keying (2FSK) modulation and demodulation technology is widely applied because it has better anti-noise performance than ASK technology and a simpler demodulation method than PSK . However, the technology based on 2FSK requires two different carriers to transmit information. WebFor an FSK modulation with coherent detection, in order to ensure orthogonality, the frequency separation between symbols is Δ f = f 2 − f 1 = 1 / 2 T. However, in case of …

In principle FSK can be implemented by using completely independent free-running oscillators, and switching between them at the beginning of each symbol period. In general, independent oscillators will not be at the same phase and therefore the same amplitude at the switch-over instant, causing sudden discontinuities in the transmitted signal. In practice, many FSK transmitters use only a single oscillator, and the process of switching to …
