Abstract
The present invention provides a control module and a method operable in a touch-sensitive apparatus for measuring noise, wherein the touch-sensitive apparatus comprises a touch-sensitive module having a plurality of first electrodes and a plurality of second electrodes that intersect in multiple regions of the touch sensitive module, said method comprising the steps of: disconnecting the first electrodes from a driving voltage source; and acquiring a plurality of voltage values of noise by measuring a plurality of voltage signals associated with the second electrodes over a plurality of measurement cycles at a predetermined operating frequency during the first electrodes without a driving voltage.
