PURPOSE: An error reducing method is provided to enhance the reliability by reducing errors occurring during the quantization process of a D/A converter and using a low pass filter and a decimal calculator. CONSTITUTION: A method comprises the steps of: initializing a counter, a decimal place, an integer place, and a data value(S11); reading digital data to be analog-converted(S16); judging whether data of a designated decimal place of the read data is 1(S21); judging whether data of a designated integer place of a counter value is 1 in case that the data of the designated decimal place is 1(S26); increasing the designated decimal place and the designated integer place by 1 in case that the data of the designated integer place of the counter is 1(S31).
