A frequency synthesiser can generate any carrier frequency within the
frequency band of the radio from a single accurate high-stability
crystal oscillator. Each of the derived frequencies has the accuracy
and stability of the source. The block diagram of the
concept of frequency synthesis is shown in Figure 9.7.
There are two main methods of frequency synthesis, the
direct frequency synthesiser and the indirect frequency synthesiser methods.
