WebFor example FreeDV 2400A uses 4FSk with a bit rate of 2400 bit/s, symbol rate of 1200 Hz, and RF bandwidth about 4*1200 = 5kHz-ish. ... i.e. symbol rate. Thus 4FSK would require half the swing ( for same Beta ) and that would imply half deltaF. We could reduce the bandwith to half, and gain 3 dB of reduced noise. ... WebIf each of the four output states (A through D) is assigned to a corresponding FSK frequency, then it is possible to transmit any two bits as a single element. Figure 8 illustrates a typical DFSK signal. Because the two binary channels are independent, they may contain any combination of synchronous and asynchronous signals.
