1. An electronic device, comprising:
a processor; and
a touch circuit configured to output, to the processor, information associated with a touch to at least one surface of the electronic device,
wherein the touch circuit is configured to:
generate first raw data including a first value associated with capacitance for each of a plurality of channels of the touch circuit,
generate a first baseline based on the first raw data,
identify whether the first raw data meets a designated condition, and
identify to reset the first baseline based on the designated condition being met,
reset the first baseline based on the designated condition being met,
wherein the designated condition includes a case in which a difference between data among the first raw data exceeds a threshold, wherein the data includes a value associated with a first channel and a value associated with a second channel, wherein the first channel and the second channel are adjacent to each other.
