Abstract

The invention discloses a system and a method for carrying out stationary processing on a digital signal, which are used for carrying out systematic stationary processing on an aperiodic, non-stationary and bounded digital signal. The method comprises the following steps of: aiming at the digital signal to be processed, searching the maximum and the minimum in a data segment; carrying out binary grouping according to the size of a signal value between the maximum and the minimum, wherein the grouping number is determined according to the actual requirements for analyzing problems; and replacing the size of signals in each group with an average value of the signals in the group. By the system and the method, the aim of carrying out systematic stationary processing on the aperiodic, non-stationary and bounded signal can be fulfilled.

Description

technical field [0001] The present invention relates to a system and method for stabilizing digital signals, in particular to a system and method for stabilizing non-periodic, non-stationary and bounded digital signals. Background technique [0002] At present, the stabilization processing of non-periodic, non-stationary, and bounded signals is in a specific field, and the processing method is selected according to the researcher's own professional judgment, such as EEG (Electroencephalogram, electroencephalogram), ECG (electrocardiogram) Signals, etc., without a systematic description and method of stabilization processing, researchers will waste time and effort. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a digital signal stabilization processing system and method, which can achieve the purpose of systematic stabilization processing of non-periodic, non-statio...
