ラジオ放送受信装置
Document Type and Number:
Japanese Patent JP4837151
Kind Code:
B2
Abstract:
A radio broadcast receiver includes a front end unit for 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 where the first frequency domain and third frequency domain overlap, and for switching, when tuning is made across the frequency domains, the 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 it is lower than the first frequency by controlling the front end unit.
