Abstract: An electronic device includes a power management circuit which supplies power from a battery to electronic components, a battery management circuit which controls connection between the battery and the power management circuit, a physical key formed on a part of the electronic device, a key control circuit which controls connection between the physical key and the battery management circuit, and a processor connected to the power management circuit. The processor is configured to transmit a signal for powering off the electronic device to the power management circuit, and when the electronic device is powered off, to control the key control circuit to connect the physical key with the battery management circuit. The power management circuit is configured to, when receiving the signal for powering off the electronic device, control the battery management circuit to disconnect the battery from the one or more electronic components included in the electronic device.

Abstract: An apparatus and method for processing a digital broadcast signal are provided. The method includes cutting off a noise frequency of a received digital broadcast signal and low-noise amplifying the noise cut-off signal, limiting an amplitude of the low-noise amplified signal spectrum to an amplitude of the digital broadcast signal spectrum, and cutting off a noise frequency of the amplitude limited signal spectrum and passing only a signal corresponding to a frequency band of the digital broadcast signal.

Abstract: A portable communication device having a panel and a touch key with a touch sensor pad integrally attached to the panel is provided. More particularly, the portable communication device includes a panel, a printed circuit board, and a control unit, wherein the portable communication device includes one or more touch sensor pads disposed on the panel for detecting a touch of the panel and for generating respective signals corresponding to the detection, and one or more connection terminals provided with the touch sensor pads, respectively, the one or more connection terminals for electrically connecting to one or more interconnection devices on the printed circuit board, respectively, for applying the signals from the touch sensor pads to the control unit.
