1. A method for converting sensing information, comprising:

  • obtaining a dual-differential sensing information;

    detecting each touch related sensing information having two peaks in a pair of zero-crossings in the dual-differential sensing information, wherein each paired zero-crossings are a zero crossing between a negative value followed by a positive value paired with a zero crossing between a positive value followed by a negative value; and

    converting the dual-differential sensing information into a sensing information with quasi all signal values, including;

    converting each touch related sensing information having two peaks in a pair of zero-crossings into signal values.
