Abstract
In a CS broadcast receiving system, when a station is to be selected, an AFC process is first performed with the frequency in the tuning circuit adjusted in units of a coarse frequency adjustment value for reception of a CS television broadcast signal. When a receive signal to be selected by the tuning circuit is not the CS television broadcast signal, the AFC process is performed with the frequency in the turning circuit adjusted in units of a fine frequency adjustment value for reception of a CS. With this arrangement, it is made possible to increase the tuning accuracy when tuning in to the CS sound broadcast signal, while the time required for tuning is shortened and the waiting time reduced when tuning in to the CS television broadcast signal and, thereby, both the requirements for reception of the CS sound broadcast signal and for reception of the CS television signal can be satisfied.
