Touch sense device including filtered value extractor and filtered value extractor

The present invention relates to a touch sensing apparatus. The touch sensing apparatus of the present invention comprises a touch panel and a touch sensor constituted to detect a touch through the touch panel. The touch sensor includes a plurality of sensing units separately connected to the touch panel through a plurality of sense lines. Each of the sensing units includes a filtered value extractor outputting valid filtered values at certain timing by calculating a plurality of input samples and a plurality of filter coefficients corresponding to a signal output from the touch panel.
