Abstract: A method for processing sensing signals in a sensing system includes receiving at least one sensing signal; performing a first operation on the at least one sensing signal to determine whether the at least one sensing signal satisfies a first predetermined condition; performing a second operation on the at least one sensing signal after a second predetermined condition is determined to be satisfied, wherein the second predetermined condition comprises a condition that the first predetermined condition is determined to be satisfied, wherein the second operation provides more sensing information than the first operation; and not performing the second operation on the at least one sensing signal after a third predetermined condition is determined to be satisfied, wherein the third predetermined condition comprises a condition that the first predetermined condition is determined to be unsatisfied.

Abstract: A noise detection device includes a drive circuit, a sense circuit and a controller. The drive circuit drives a plurality of drive lines having a first polarity pattern and a second polarity pattern, wherein an operation of the first polarity pattern and the second polarity pattern substantially equals zero over a predetermined time period. The sense circuit senses a plurality of sense signals from at least one sense line during the predetermined time period. The controller derives a magnitude of a noise signal from the at least one sense line according to the sense signals.
