In processing for normalizing a P-bit input digital signal, which is expressed by binary notation, to 2M−1 (0<M≦̸P) tones, upper M bits of the input digital signal are repetitively concatenated until P bits are reached, a concatenated signal obtained as a result of concatenation is compared with the input digital signal, and a value indicated by the upper M bits or a value obtained by subtracting 1 from the value indicated by the upper M bits is determined as a normalized value depending on the comparison result.
