The processing system includes demodulators, and is configured to simultaneously drive at least a subset of the transmitter electrodes using a multitude of transmitter signals with unique frequencies. The processing system is also configured to receive, on the receiver electrode, a resulting signal, and demodulate, using the plurality of demodulators, the resulting signal to generate a multitude, of sensing signals. Each of the of the demodulators operates on a different frequency of the unique frequencies."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-frequency-region touch sensing","description":"An input device includes transmitter electrodes disposed in a sensing region of the input device, a receiver electrode in the sensing region, and a processing system.
