PROBLEM TO BE SOLVED: To reproduce an original signal continuously and faithfully. SOLUTION: An extraction section 9 extracts a signal while sectioning for every block formed continuously and having an overlapped region on the time axis, and since a calculating section 11 detects the signal difference (Δϕ) in the overlapped region and supplies the calculation data of a combination to be continuous along with the signal difference (Δϕ) data to a coupling section 12, the coupling section 12 can perform corrected coupling such that the signal difference (Δϕ) becomes zero and an original signal having a signal waveform (frequency spectrum) faithful to the input signal can be reproduced and outputted.
