Abstract
A digital signal processing apparatus includes: a detection section; a prediction section; and a decision section. The detection section is configured to detect a signal position at which a signal component may possibly have been removed from a digital signal in a signal conversion processed state upon the signal conversion process. The prediction section is configured to predict, based on data at correlating portions of the digital signal in the signal conversion processed state in a demodulation frequency band, data at the signal position prior to the removal detected by the detection section. The decision section is configured to decide whether or not the absolute value of the data at the signal position prior to the removal predicted by the prediction section is lower than a resolution at the signal position and adopt the predicted data prior to the removal as interpolation data.
