Essay on fsk modulation and demodulation
Fsk demodulation with matlab i was looking for a way to simulate fsk modulation/demodulation techniques and to look into the effect of different sampling rates i also wanted to see if there was a more efficient way to demodulate fsk than fast fourier. Reception of serial, low rate, data transmitted employing binary fsk (frequency shift keying) modulation the fsk demodulation process is implemented using an algorithm for a digital version of a pll (phase. The key difference between modulation and demodulation is that modulation is to transfer the message signal by adding it with the carrier signal while demodulation is the process of filtering out the actual message signal from the carrier signal.
