Abstract
A method for multi-touch detection on a grid based capacitive sensor includes transmitting consecutively a first and then a second sequence of a Golay pair of sequences on a first driver line of a grid based capacitive sensor and transmitting the first and then the second sequence of a Golay pair of sequences on a second driver line, at a predefined delay with respect to transmission on the first driver line. Output on a receiver line of the grid based capacitive sensor is sampled and output originating from the first driver line is separated from output originating from the second driver line. The presence of an input object is detected responsive to the output as separated.
