Patent ID: 8606202

Claim:
A radio receiver apparatus which seeks and receives, within a reception frequency band, a signal from a broadcast station corresponding to a broadcast wave having signal intensity greater than a predetermined threshold, and presets to the radio receiver apparatus a frequency of the sought and received signal as a frequency of a broadcast station to be received, comprising: an intensive input determination unit configured to determine an intensive electric field station in the reception frequency band of broadcast wave; and a spurious station calculation/determination unit configured to calculate, when m-stations (in is an integer number equal to or more than 2) as the intensive electric field stations are determined by the intensive input determination unit, repeated combinations with respect to N-frequencies (N is an integer number equal to or more than 2) from m-frequencies utilized in the m-stations, perform addition and subtraction operations on frequencies of each of the repeated combinations, find a frequency as a spurious frequency of Nth-order harmonies from among the frequencies acquired through the addition and subtraction operations, the frequency to be found being included in the reception frequency band, and control the spurious frequency of Nth-order harmonics not to be preset to the radio receiver apparatus even though signal intensity of a received signal having said spurious frequency of Nth-order harmonics exceeds the predetermined threshold.
