CIRCUIT FOR CORRECTING DATA

摘要

PROBLEM TO BE SOLVED: To accurately obtain true value data by correcting variation from data with much variation influenced by each kind of noise or distortion and an error in a device. SOLUTION: A touch panel 1 outputs position data 6 corresponding to the contact position of a key input. An A/D converter 2 converts the analog value of the position data 6 into a digital value, and outputs A/D data 7. A maximum and minimum value detector 3 fetches the A/D data 7, detects the maximum value and minimum value of the data, and outputs detected data 8. A maximum and minimum value deletor 4 outputs data 9 for equalization obtained by deleting the maximum value and the minimum value from the detected data 8. An equalizer 5 equalizes the data 9 for equalization, and outputs position data 10.
