Abstract

A method includes transmitting a Continuous Wave Frequency Modulated (CWFM) signal on a first drive line of a grid based capacitive sensor and transmitting the CWFM signal with an imposed delay on a second drive line of grid based capacitive sensor simultaneously with transmission of the CWFM signal on the first drive line. Output on a receive line is correlated with the CWFM signal, Fourier transformation is performed on the correlation of the output and coordinates of an object interacting with the grid based capacitive sensor is identified based on frequency and phase information determined from the Fourier transformation.
