A high-frequency receiving apparatus includes a phase pull-in circuit
controlling an oscillator so as to eliminate a phase difference, a
frequency pull-in circuit controlling the oscillator so as to eliminate a
frequency difference, a frequency shift circuit shifting an oscillation
frequency of the oscillator by a prescribed frequency when the frequency
difference is large, and a control signal generation circuit controlling
those circuits according to an algorithm selected from a plurality of
algorithms corresponding to, for example, a symbol rate. Therefore, a
wide range of frequency can rapidly be pulled regardless of the level of
the symbol rate.
