RADIO BROADCAST RECEIVER, BROADCAST FREQUENCY DETECTION METHOD, BROADCAST FREQUENCY SEARCHING METHOD AND BROADCAST FREQUENCY SCANNING METHOD

摘要

PROBLEM TO BE SOLVED: To provide "a radio broadcast receiver, a broadcast frequency detection method, a broadcast frequency searching method and a broadcast frequency scanning method" capable of detecting the frequency in which broadcasting has been performed more accurately.SOLUTION: A frequency fm has a reception strength (S meter value) of equal to or larger than a threshold Th0, and the reception strength of the frequency fm is larger than the reception strength of adjacent frequencies fm-1 and fm+1 separated by 1 step, by X or more. The frequency fm is detected as a broadcast reception signal, in which receivable broadcast has been performed. The larger the reception strength (S meter value) of the frequency fm, the larger the value of X is set.
