Abstract: An electronic device includes: An electronic device includes a first communication module and a second communication module configured to perform wireless communication, a spread spectrum clock generator (SSCG), a memory, and a processor. The processor is configured to execute instructions to set a spread spectrum method and a spread ratio of the SSCG, determine whether the electronic device is communicatively coupled to at least one of a first and a second wireless communication, identify a frequency band of a channel of the at least one of the first and the second wireless communication, determine whether at least one of a frequency and multiplication frequencies of the frequency is included by the frequency band of the channel, and maintain the spread spectrum method and the spread ratio causing the SSCG to generate a spread spectrum clock signal based on first spread spectrum method and the spread ratio.

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.
