Abstract
A digital signal receiving apparatus includes a detection-judging portion having a first smoothing filter generating a first smoothed signal by smoothing an auto-correlation signal and judging a possible presence of a desired signal when a signal level of the first smoothed signal is greater than a reference level and an absence of the desired signal when being smaller than the reference level. The smoothing filter includes a limiting portion limiting a fluctuation width of the first smoothed signal; and an adjusting portion configured to adjust the fluctuation width of the first smoothed signal limited by the limiting portion to be reduced while an elapsing time after the detection-judging means judges the possible presence of the desired signal is increasing.
