Abstract
The present invention is a method and an apparatus for digital signal processing. The method extracts a plurality of data which is not zero or repeated and recognizes a plurality of coordinate data corresponding to the extracted data. The method saves memory space and makes digital signal processing more efficient.
Claims14
A method for digital signal processing, comprising the following steps:
- inputting a digital signal;
- extracting a plurality of first data which is not meaningless from the digital signal;
- recognizing a first coordinate data corresponding to each first data;
- processing the first data through an arithmetic process to obtain a processed data;
- extracting a plurality of second data which is not meaningless from the processed data;
- recognizing a second coordinate data corresponding to each second data;
- combining the second data and the second coordinate data to obtain a processed digital signal;
- outputting the processed digital signal.
