ABSTRACT:
An electromagnetic digitizer which applies twin rate charging and discharging proportional to determine center position of a cursor. It makes use of the largest and second largest voltages detected by sense rings, the second largest is charged for a standard time, and the largest one is discharged till zero potential, and then the discharge time is compared with sum of the standard time and discharge time, result of which is multiplied by a constant to get center position of the cursor.
