ABSTRACT:
An analog-digital converting apparatus includes: an analog-digital converting unit that performs a conversion from an analog input signal into a digital output signal; a buffer unit that temporary stores the digital output signal for a plurality of samples and outputs the samples in time-series; a clipping detecting unit that detects a first sample having a signal value corresponding to a clipping level of the analog-digital converting unit from among the samples of the digital output signal; and an interpolating unit that rewrites the signal value of the first sample stored in the buffer unit into an estimated signal value that is obtained by estimating a signal value at a time corresponding to a time of the first sample by an interpolation using at least one of (1) a set of second and third samples that are samples previous to the first sample and (2) a set of fourth and fifth samples that are samples subsequent to the first sample.
