Abstract
A touch sensing system can demodulate sensor data using a dynamically adjusted demodulation waveform and/or demodulation window. The demodulation waveform and/or demodulation window can be dynamically adjusted to account for dynamically changing noise in a touch sensing system. The system can dynamically adjust the demodulation window based on noise measured by the touch sensing system to generate an optimized or otherwise noise-tailored window to suppress detected noise. In some examples, the noise measured by the touch sensing system can be sampled from sense channels localized to a detected touch.
