METHOD AND APPARATUS FOR SIGNAL PROCESSING |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a method for signal processing which has high noise reduction effect and high distortion removal effect. SOLUTION: An input signal V<SB>in</SB>is weighted with a first weight k<SB>i</SB>in the form of (n) (≥3) divided signals. The divided signals which have been weighted are processed by (n) signal processing means 1 to (n) which perform the same signal processing. The signal-processed divided signals are weighted with a second weight l<SB>i</SB>and added together to obtain an output signal V<SB>out</SB>. The weights k<SB>i</SB>and l<SB>i</SB>are selected to improve the noise reduction effect and remove distortion. COPYRIGHT: (C)2007,JPO&INPIT
