Digital data filtering method, apparatus, and terminal device

A digital data filtering apparatus comprising a processor and a memory storing instructions executable for the processor, wherein the instructions function as:

• a data collecting module configured to collect first digital data and second digital data of a current collection period;
• a current digital sample data processing module configured to obtain a current digital sample data by summing the first digital data and the second digital data and obtaining an arithmetic mean;
• a data change trend determining module configured to determine a data change trend of the current digital sample data according to the current digital sample data and a digital sample data of a previous collection period;
• and
• a filtered data processing module configured to choose a filtering method from a group of prestored filtering methods according to the data change trend, and filter the current digital sample data using the filtering method to obtain a filtered data.

A terminal device for digital data filtering, comprising:

• one or more processors;
• a memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs comprises:
• instructions for collecting first digital data and second digital data of a current collection period;
• instructions for obtaining a current digital sample data by summing the first digital data and the second digital data and obtaining an arithmetic mean;
• instructions for determining a data change trend of the current digital sample data according to the current digital sample data and a digital sample data of a previous collection period;
• and
• instructions for choosing a filtering method from a group of restored filtering methods according to the data change trend, and filtering the current digital sample data using the filtering method to obtain a filtered data.
