PROBLEM TO BE SOLVED: To effectively execute an adaptive filter operation performed with deranging. SOLUTION: The method for determining whether a filtering calculation is applied to input data samples by executing a logic calculation of logic data items comprises a step (a) of converting the logic calculation to an equivalent logic calculation including the filtering calculation, a step (b) of storing the input data samples and the logic items in data words, a step (c) of applying the filtering calculation to the data words, using a data processor, and storing the filtered data samples and corrected logic data items in the data words, a step (d) of comparing the corrected logic data items with specified references, and a step (e) of taking either the input data samples or data samples fetched from the filtered data samples, according to the comparison in the step (d) as the output data samples. |
