Abstract
An electronic device and a method for operating an electronic device are provided. The electronic device includes a first circuit board, a second circuit board, a signal line connecting the first circuit board and the second circuit board, a processor disposed on the first circuit board and outputting a pulse signal through the signal line, a parasitic capacitance pattern disposed around the signal line and generating a parasitic capacitance by the pulse signal, and an amplifier disposed on the second circuit board and amplifying a signal generated by the parasitic capacitance, wherein the processor identifies whether the signal line is abnormal, based on the amplified signal obtained from the amplifier.
