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 …

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.
