Abstract
A simplified decoder for a decoder for 2-dimensional input devices with less number of pads is disclosed. Two pads are used to represent the addresses in one dimension of the input means in the 2-dimensional input device. Two capacitors are charged through a number of resistors, which number is decided by the number of addresses of said dimension. The time difference in charging the capacitors is measured to determine the address of an actuated input means in said dimension.
