Method for stabilizing digital signal data

The invention discloses a digital signal data stabilizing method, which comprises the following steps of: (a) judging whether next input data is greater than previous output data, if so, adding a basic value to a trend value, and then executing a step (c), and if not, executing a step (b); (b) judging whether the next input data is smaller than the previous output data or not, if yes, subtracting the basic value from the trend value, and executing the step (c), and if not, executing the step (c); (c) judging whether the trend value is greater than a positive threshold value, if so, subtracting the trend adjustment coefficient from the previous output data, and if not, executing the step (d); and (d) judging whether the trend value is smaller than a negative threshold value, if so, adding the trend adjustment coefficient to the previous output data, and if not, outputting the previous output data. 本发明公开数字信号数据的稳定方法，包含步骤：(a)判断下一输入数据是否大于前一输出数据，若是，将趋势值加上基础值，接着执行步骤(c)，若否，执行步骤(b)；(b)判断下一输入数据是否小于前一输出数据，若是，将趋势值减去基础值，执
