Title: Data conversion device and method
Inventor: MATSUNAGA KEIJI
IPC: H03M7/30
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To eliminate quantized noise and to restore the delicate musical signals by extending the bit length for the frequency axis components which is smaller than a specific level among those digital data which are converted into the frequency axis components. SOLUTION: A conversion means 2 performs the fast Fourier transform to convert the digital data, sampled on time axis and having the effective bit number N into the frequency axis components, after dividing the data into specific blocks. In the fast Fourier transform, a solution of a discrete Fourier conversion is obtained by an expression I and with a small number of multiplication times. Then the frequency-axis component of the block to be converted is obtained by an estimation means 4. A transforming means 7 transforms the frequency-axis components smaller than a specific level, with that obtained by the means 4 among those frequency-axis components which are converted by the means 2. Thus, the quantized noises are eliminated, and the delicate musical signals can be restored.
