To mitigate the effects from these capacitive couplings, the input device drives a modulated capacitive sensing signal onto a plurality of sensor electrodes in parallel. The sensor electrodes are coupled to respective analog front ends (AFEs) which generate an output signal for each of the sensor electrodes. The input device combines the output signals for the sensor electrodes to generate a normalization value. For example, the output signals may be digital values which are summed by the input device to generate the normalization value. The input device then divides each of the output signals by the normalization value to result in a normalized signal corresponding to each of the sensor electrodes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Normalizing capacitive sensing measurements to reduce effects of low ground mass and noise","description":"An input device can be capacitive coupled to earth ground and noise sources which can interfere with the ability of the input device to detect an input object.
