Abstract
An input device comprises a processing system coupled with a plurality of receiver paths. The processing system comprises a first capacitor and a bypass switch. The first capacitor is configured to be selectively coupled with the plurality of receiver paths. The bypass switch is configured for bypassing the first capacitor. The processing system is configured to selectively couple a first receiver path of the plurality of receiver paths with the first capacitor; acquire a measurement of a first resulting signal from at least one of the first receiver path or a second receiver path of the plurality of receiver paths while the first receiver path is coupled with the first capacitor and while the bypass switch is not bypassing the first capacitor; and determine whether the first receiver path is ohmically coupled with the second receiver path based on the measurement of the first resulting signal.
