Abstract: Disclosed are an electronic device and a method for generating a clock signal within a camera module. The electronic device includes a processor, and a camera module, wherein the camera module may include a clock generation circuit configured to generate a second clock signal, the second clock signal being independent from a first clock signal, the first clock signal being generated by the processor, an optical correction circuit configured to be driven based on the second clock signal, and an image sensor configured to be driven while being synchronized with the optical correction circuit based on the second clock signal, wherein the processor may be configured to transfer a control command to the camera module, based on an input for driving the camera module and to acquire at least one image through the synchronized optical correction circuit and image sensor based on the second clock signal.

Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than 4th generation (4G) communication systems such as long term evolution (LTE). In a wireless communication system, a transmission apparatus comprises at least one antenna port for transmitting/receiving a signal, an analogue filter for selecting the frequency of the signal, and a voltage standing wave ratio (VSWR) detection unit for measuring the VSWR of the antenna port, wherein the VSWR detection unit is configured to detect both a forward signal and a reverse signal for an input terminal of the analogue filter, to determine the respective power values of a forward signal and a reverse signal for an output terminal of the analogue filter by applying characteristic parameters of the analogue filter to the detected forward signal and reverse signal, and to determine the VSWR of the antenna port on the basis of the respective power values of the forward signal and the reverse signal for the output terminal of the analogue filter.

Abstract: According to an embodiment, a printed circuit board and an electronic device is disclosed. The printed circuit board includes a first pattern configured to be formed in a first layer. The printed circuit board also includes a second pattern configured to be formed in at least one second layer under the first layer. The printed circuit board also includes a via configured to electrically connect the first pattern to the second pattern. The printed circuit board further includes a recess configured to be formed by removing at least a portion of an area in which the via is formed and to electrically separate the first pattern from the second pattern.
