Abstract:
1. A radio broadcast receiver having two tuners for independently receiving different frequencies in a receiving band with a receiving bandwidth greater than an intermediate frequency and not greater than twice the intermediate frequency, the radio broadcast receiver comprising: a front end unit for carrying out tuning by changing a local oscillation frequency; and a control unit for managing by dividing the receiving band into a third frequency domain including a third frequency obtained by subtracting the intermediate frequency from an upper end frequency of the receiving band, a first frequency domain including a first frequency obtained by adding the intermediate frequency to a lower end frequency of the receiving band, and a second frequency domain in which the first frequency domain and the third frequency domain overlap, and for switching, when a change in tuning is made across the frequency domains, a local oscillation frequency to an upper local oscillation frequency when the tuning frequency is higher than the third frequency by controlling the front end unit, and to a lower local oscillation frequency when the tuning frequency is lower than the first frequency by controlling the front end unit.
