Abstract: A method includes identifying a first plurality of drive frequencies at which drive electrodes of a touch-sensitive display of an electronic device are driven, wherein the first plurality of drive frequencies includes a first frequency and a second frequency. A first noise value at the first frequency is determined. When the first noise value meets a first threshold value and the first noise value is less than a second threshold value that is greater than the first threshold value, a second noise value at the second frequency is determined by the electronic device and, in response to determining that the second noise value is less than the first threshold value, driving the drive electrodes at the second frequency. When the first noise value meets the second threshold value, a third frequency at which the drive electrodes are driven is identified by the electronic device, wherein the third frequency is not one of the first plurality of drive frequencies.
