Abstract

A method for rapidly analyzing and editing data files with a number GUI'"'"'s and an adaptive decimation ratio in a computer allows processing data files and signal data files within a given data segment for a better fit into a limited-size working space buffer and provides improved resolution of data segments in a simplified way using GUI'"'"'s that allow the user to point and click at a computer screen instead of performing manual calculations. A large data segment is adaptively decimated to a smaller size automatically so that a lower resolution version of the data segment will be loaded into a fixed-size small buffer in hardware working space for further data editing. The decimation and loading process will be repeated until the user finds the desired data-section of interest.
