Abstract
According to an embodiment, an electronic device may include: a processor; and a touch circuit configured to output, to the processor, information associated with a touch on at least one surface of the electronic device. The touch circuit may be configured to: generate first raw data including a first value associated with capacitance for each of multiple channels of the touch circuit; generate a first baseline on the basis of the first raw data; identify whether the first raw data satisfies a designated condition; and identify whether the first baseline is reset, on the basis of whether the raw data satisfies the designated condition.
