<P>PROBLEM TO BE SOLVED: To provide a noise removing device that can eliminate discontinuity at a connection point between both blocks nearly without increasing an operation quantity while keeping the number of samples as it is by correcting waveforms of both the blocks which become adjacent on a time base as a result of windowing so that they are closer to each other. <P>SOLUTION: If the discontinuity is generated at the connection point between both the blocks which become adjacent on the time base, a CPU 100 performs processing for finding a correction quantity of smoothing processing (steps S3000, S3010). Then a difference value per sample is found from the correction quantity of the smoothing processing (step S3020). Then processing for adding a numeral calculated based upon the difference value and a variable J to the sample value of a sample at a position corresponding to the variable J is carried out (step S3040). Further, processing for subtracting the numeral calculated based upon the difference value and variable J from the sample value of the sample at the position corresponding to the variable J is performed (step S3050). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
